Thermally induced particle emission as possible formation process of β+-nuclei

Термически индуцированная змиссия частиц как воэможный процесс обраэования β+-ядер

Summary

We investigate the possible production of the neutron-poor heavy nuclei (essentially the p-nuclei in the nomenclature of Burbidgeet al.) in a short-time «disintegration process» at high temperatures, followed by β+-decay. In order to obtain an abundance distribution which shows good agreement with the empirical data, an initial abundance distribution of «seed nuclei» which consists of all other abundance components is possible. A temperatureT 0 ofkT 0 ≈ 550 keV must have prevailed for a time as short as 10−8 s.

Riassunto

Si indaga sulla possibile produzione di nuclei pesanti poveri di neutroni (essenzialmente i nuclei p della nomenclatura di Burbidgeet al.) in un «processo di disintegrazione» a tempo breve ad alta temperatura e seguito da decadimento β+. Allo sbopo di ottenere una distribuzione di abbondanze che si mostri in buon accordo con i dati empirici, è possibile una distribuzione iniziale di abbondanza di «nuclei di inseminazione» che consista di tutti gli altri componenti di abbondanza. Per un tempo di soli 10−8 s deve aver prevalso una temperaturaT 0 dikT 0 ≈ 550 keV.

Реэюме

Мы исследуем воэможное обраэование тяжелых ядер с недостатком нейтронов (особенно р-ядер в номенклатуре Бурбиджа и др.) в « процессе расше-пления » с малым временем при высоких температурах, с последуюшим β+-распа-дом. Для получения распределения распространенности, которое обнаруживает хорощее согласие с змпирическими данными, окаэывается воэможным испольэо-вать начальное распределение распространенности « эатравочных ядер », которое согласуется со всеми другими компонентами распространенности. ТемператураT 0 (kT 0≈550 KзB) должна превалировать для времен короче 10−8 с.
