Ниэколежашие уровни в47V

Il Nuovo Cimento A (1965-1970)

Summary

The low-lying levels of47V have been investigated through the47Ti(p, n)47V reaction with proton energies between 3.6 and 5.3 MeV and through the40Ca(10B, 2pn)47V reaction atE 10B=25 MeV. From single and γ-γ coincidence spectra the decay scheme has been obtained. Angular distributions in the heavy-ion reaction, conversion coefficient and lifetime measurements have been performed to determine the multipolarity of transitions and to assign spin and parity of several levels.

Riassunto

Sono stati studiati i livelli di bassa energia del47V tramite le reazioni47Ti(pn)47V, con un’energia dei protoni variabile da 3.6 MeV a 5.3 MeV, e40Ca(10B, 2pn)47V ad un’energia degli ioni10B di 25 MeV. Lo schema di decadimento è stato dedotto dall’analisi degli spettri singoli e di coincidenza γ-γ. Mediante misure di distribuzioni angolari nella reazione con ioni pesanti, di coefficienti di conversione e di vite medie si è potuto determinare la multipolarità di alcune transizioni ed assegnare lo spin e la parità di diversi livelli.

Реэюме

Были исследованы ниэколежашие уровни47V, испольэуя реакцию47TI(p, n)47V при знергиях протонов от 3.6 до 5.3 МзВ и реакцию40Ca(10B, 2pn)47V приE 10B=25 МзВ. Иэ синглетного спектра и спектра г-г совпадений была получена схема распада. Угловые распределения в реакции с тяжелыми ионами, иэмерения козффициента конверсии и времени жиэни поэволяют определить мультипольность переходов и приписать спин и четность некоторым уровням.
