( La percentuale isotopica naturale è indicata da Pisn. Le sezioni d'urto elastico, Se, e di assorbimento Sa, sono aree date in fermiquadri essendo il fermi un femtometro ossia un milionesimo di miliardesimo di metro e rappresentano l'area efficace del nucleo dell'atomo contro cui il neutrone può scontrarsi facendo uno scontro elastico ossia rimbalzando o uno scontro con assorbimento ossia venendo catturato )
L'Universo è fatto di questi atomi...

Sezioni di scontro con neutroni, elastico e di assorbimento degli elementi in natura

Le aree delle sezioni d'urto delle miscele naturali degli isotopi sono dati in fermiquadri ossia in femtometri quadri. Il primo valore è l'area di scontro elastico ed il secondo è l'area di scontro con cattura ossia assorbimento del neutrone nel nucleo.

Il valore 0 indica dati non disponibili...

Codice dei colori usati per indicare l'emivita degli isotopi : * colore magenta = secondi o meno, * colore rosso = minuti di 60 secondi, * colore verde = ore di 60 minuti, * colore blu = giorni di 24 ore, * colore blu scuro = anni gregoriani ossia 365.2425 giorni, * colore nero = emivita maggiore 10¹⁶ secondi ossia di circa 317 milioni di anni.

Isotopi

Uso [5*A-2*P,P-2*A] ossia X=5*A-2*P, P-2*A per cui deduco il peso atomico con la formula: P=2*X+5*Y e il numero atomico con la formula: A=X+2*Y.

P =

A =

A mio parere sono poco reperibili i dati propriamente nucleari ossia le sezioni d'urto e di assorbimento che sono molto diverse da un isotopo all'altro !
Un grazie al NIST !

Vedere qui: http://www.elegio.it/omnia/nu/elemen-monoiso.html

Notare come l'elio sarebbe l'elemento meno assorbente se l'isotopo 4 non fosse leggermente inquinato dall'isotopo 3 prodotto dal decadimento del trizio e notare come sarebbe MERAVIGLIOSO l'isotopo 208 del piombo se non costituisse solo circa il 52% del piombo ma se fosse puro ossia non inquinato dagli altri isotopi che un po' catturano i neutroni ma molto più di lui che ha una tendenza a catturare i neutroni piccolissima !.
Una strategia per me logica, in mancanza di un adeguato sistema di separazione degli isotopi, sarebbe quella di andare ad estrarre il piombo dalle miniere di torio dato che l'isotopo 208 é l'ultimo figlio della catena di decadimento del torio per cui nelle miniere di torio il poco piombo presente dovrebbe essere molto meno inquinato dai suoi isotopi piò leggeri...

All of this data was taken from the Special Feature section of neutron scattering lengths and cross sections of the elements and their isotopes in Neutron News, Vol. 3, No. 3, 1992, pp. 29-37.

The contents of the columns are as follows:

Column Unit Quantity
1 --- Isotope
2 --- Natural abundance (For radioisotopes the half-life is given instead)
3 fm bound coherent scattering length
4 fm bound incoherent scattering length
5 barn bound coherent scattering cross section
6 barn bound incoherent scattering cross section
7 barn total bound scattering cross section
8 barn absorption cross section for 2200 m/s neutrons

Note: 1fm=1E-15 m, 1barn=1E-24 cm^2, scattering lengths and cross sections in parenthesis are uncertainties.

Varie info nucleari

Isotopi dell'uranio e del plutonio

U [232U: α emivita=68.9 anni] Cattura neutronica (neutroni termici 73 barn, integrale di risonanza 280 barn) ma, stranamente, ha una sezione di cattura di fissione elevata: (neutroni termici 75 barn , integrale di risonanza 380 barn). È un forte emettitore di raggi γ e viene prodotto inevitabilmente quando si trasforma il Torio 232 in Uranio 233 che è fissile come lo è l' Uranio 235. Per questa ragione l'Uranio 233 non può essere usato per fare bombe a fissione nucleare.

U [233U: α emivita=1.592·10⁵ anni] Fissile

U [234U: α emivita=2.455·10⁵ anni] Non è fissile ma ha una cattura neutronica molto forte ( neutroni termici 100 barn , integrale di risonanza 700 barn ) per cui, se la sua concentrazione iniziale, rispetto all' Uranio 235 fosse elevata ( per voluta contaminazione effettuata anti proliferazione nucleare ) l'arricchimento dell'uranio produrrebbe non uranio 235 quasi puro ma pieno di Uranio 234 e quindi non usabile per fare bombe a fissione nucleare.

U [235U: α emivita=7.0038·10⁸ anni] Fissile

U [236U: α emivita=2.348·10⁷ anni] Questo uranio non è fissile ma non è neppure un forte assorbitore di neutroni per cui non è molto utile come inquinante dell' Uranio 235 per ostacolare l'uso del fissile per fare bombe a fissione nucleare.

U [237U: β emivita=6.75 giorni ] inutile sotto ogni aspetto dato che la sua emivita è molto breve per cui lui decade velocissimamente e dunque non è accumulabile.

U+Pu [238U: α emivita=4.468·10⁹ anni] l'Uranio naturale è fatto praticamente tutto da questo isotopo tranne lo 0.7% di Uranio fissile 235.
[238Pu α emivita=87.74 anni] Il suo uso è importante come generatore di calore per decadimento radioisotopico. Avendo una emivita lunga, circa 88 anni, può andare avanti per decenni a produrre calore e, dopo 88 anni la sua produzione di calore sarà solo dimezzata...

Pu [239Pu α emivita=2.41·10⁴ anni] Fissile

Pu [240Pu α emivita=6.5·10³ anni] Forte ostacolo all'uso del plutonio fissile per fare bombe a fissione nucleare.

Pu [241Pu β emivita=14 anni] Fissile Anche se è fissile non è usabile per fare bombe a fissione nucleare perché decade in modo piuttosto veloce e quindi è un forte generatore di calore per decadimento radioisotopico e dunque scalderebbe fortemente la bomba col rischio di distruggerla...

Pu [242Pu α emivita=3.73·10⁵ anni] Ostacolo all'uso del plutonio fissile per fare bombe a fissione nucleare.

Pu [243Pu α emivita=4.956 ore] Con una vita tanto breve da scomparire rapidamente e non essere accumolabile.

Pu [244Pu α emivita=8.08·10⁷ anni] Inutile per scopi bellici ma così ricco di neutroni da essere utile per studi di fisica nucleare ossia per produrre nuclei di Copernicio [http://en.wikipedia.org/wiki/Copernicium], Flerovio [http://en.wikipedia.org/wiki/Flerovium] e Livermorio [http://en.wikipedia.org/wiki/Livermorium] ossia per tentare di raggiungere l' Isola di stabilità transuranica. Vedere : http://en.wikipedia.org/wiki/Island_of_stability. Sono ricerche portate avanti da Jurij Colakovič Oganesian http://it.wikipedia.org/wiki/Jurij_Colakovi%C4%8D_Oganesian riconosciuto autore della dintesi del Flerovio : http://www.rsc.org/chemistryworld/news/2009/september/30090902.asp

Una mia rozza traduzione di un articolo dedicato alla conferma della sintesi del Flerovio

Per confermare l'esistenza e le emivite di isotopi di elementi, il Flerovio che ha il numero atomico 114 ( ossia 114 protoni nel nucleo ) rappresenta un grande passo avanti nella ricerca di un "isola di stabilità" la stuzzicante previsione dei fisici teorici, dove le emivite di elementi superpesanti potrebbero essere valutate in ore, giorni o addirittura milioni di anni. "Ci sono alcuni calcoli che dicono che un nucleo con 114 protoni e 184 neutroni ossia di peso atomico 298, sarebbe addirittura stabile", dice Nitsche. I due isotopi confermati dal gruppo di Berkeley, peso atomico 286 e numero atomico 114 e peso atomico 287 e numero atomico 114, hanno tempi di dimezzamento ( ossia emivita ) di 0.13 secondi e 0.5 secondi, rispettivamente, ma i dati russi per un isotopo più pesante, peso atomico 289 e numero atomico 114 ottenuti bombardando l'isotopo 244 del Plutonio con l'isotopo 48 del Calcio, suggeriscono una emivita di 2.6 secondi, dunque superiore.
"L'emivita aumenterà quando ci avvicineremo ai 184 neutroni" dice Nitsche, "2,6 secondi sono un'eternità in assoluto e la gente sta cominciando ora a pianificare esperimenti di chimica per vedere se il Flerovio di numero atomico 114 si comporta come previsto teoricamente nella tavola periodica degli elementi".
Ma Nitsche sottolinea che ci sono ancora almeno nove neutroni per arrivare al punto di massima stabilità previsto, e per ottenere isotopi più pesanti di quelli attualmente ottenuti non ø facile.
"Alcuni sostengono che l'isola non potrebbe esistere fino agli elementi di numero atomico 120 o addirittura 126, o che ci potrebbe semplicemente essere un progressivo aumento della stabilità".
Egli aggiunge che gli esperimenti per ottenere elementi più pesanti sono molto importanti per aiutare i teorici che cercano di capire il nucleo e di fare previsioni sensate. Oganessian è anche lui desideroso di trovare elementi più pesanti, dicendo che il suo gruppo ha appena iniziato una collaborazione con gli scienziati negli Stati Uniti per cercare di produrre l'elemento di numero atomico 117.

Oh poveretto ! E' morto o lo hanno ammazzato ? UC Berkeley chemistry professor and Lawrence Berkeley National Laboratory scientist Heino Nitsche died in his sleep Tuesday at the age of 64.

http://www.elegio.it/omnia/20120830.xhtml La mia insolita tavola degli isotopi stabili o quasi stabili ( più di 1 secondo di emivita )

Foto ricordo di fine anno 2015 ( Il mitico prof. Carlo Lombardi a cui deve tanto l'allievo gufonoioso )

Ecco uno dei rari sostenitori del gufonoioso.. io_me

Un lavoro iniziato nel 2012 e mai completato con i dati di tutti gli elementi importanti...

L'Universo è fatto di questi atomi...

Sezioni di scontro con neutroni, elastico e di assorbimento degli elementi in natura

Isotopi

Isotopi leggeri

Isotopi pesanti

Ora ( 2015 ) la Wikipedia fornisce dati degli isotopi anche in italiano

Fonte dei dati

Elementi

Proprietà di isotopi importanti

A mio parere sono poco reperibili i dati propriamente nucleari ossia le sezioni d'urto e di assorbimento che sono molto diverse da un isotopo all'altro ! Un grazie al NIST !

Varie info nucleari

Isotopi dell'uranio e del plutonio

Una mia rozza traduzione di un articolo dedicato alla conferma della sintesi del Flerovio

48Ca+249Bk Fusion Reaction Leading to Element Z=117: Long-Lived α Decaying 270Db ( emivita di circa un'ora ) and Discovery of 266Lr
