Summary
Reaction cross-sections have been measured for some rareearth nuclei,i.e.,138Ba,139La,140Ce,141Pr,142Nd(n, p);138Ba,140Ce,141Pr,142Nd,144Sm(n, 2n);138Ba(n, α);138Ba,139La,141Pr(n, γ) by activation with (14.0±0.2) MeV neutrons. The results have been compared with the predictions of approximate formulae based on the statistical model and a good agreement has been found.
Riassunto
Sono state misurate con neutroni da (14.0±0.2) MeV le seguenti sezioni d’urto di attivazione:138Ba,139La,140Ce,141Pr,142Nd(n, p);138Ba,140Ce,141Pr,142Nd,144Sm(n, 2n);138Ba(n, α);138Ba,139La,141Pr(N, γ). I risultati sperimentali sono in buon accordo con i valori calcolati con formule approssimate basate sul modello statistico.
Реэюме
Были иэмерены поперечные сечения реакций для некоторых редкоэемельных ядер, таких как:138Ba,139La,140Ce,141Pr,142Nd(np);138Ba,140Ce,141Pr,142Nd,14Sm(n, 2n);138Ba(n, α);138Ba,139La,141Pr(n, γ) посредством активации нейтронами (14.0±0.2) МзВ. Реэультаты были сравнены с предскаэаниями приблиэительной формулы, основанной на статистической модели, и получено хорощее согласие.
