Summary

Angular distribution for29Si(3He, α)28Si and30Si(3He, α)29Si reactions induced by 10 MeV3He particles have been measured. We have found experimental evidence that the silicon isotopes contain in their ground state large core-excited components. Neutron occupation numbers ford 5/2,d 3/2,s 1/2 andf 7/2 orbits are obtained for the ground state of the silicon isotopes and compared with the shell-model prediction.

Riassunto

Sono state studiate le reazioni30Si(3He, α)29Si e29Si(3He, α)28Si ad una energia del fascio incidente di 10 MeV. Dai risultati sperimentali sono state ricavate le probabilità di occupazione dei neutroni nelle orbite 1d 3/2, 2s 1/2, 1d 3/2 ed 1f 7/3, confrontandole con le previsioni del modello a strati.

Резюме

Были измерены угловые распределения для реакций29Si(3He, α)28Si и30Si(3He, α)29Si, производимых частивами3He с энергией 10 МэВ. Мы получили экспериментальное подтверждение, что изотопы кремния содержат в своих основных состояниях возбужденные компоненты большого остова. Получены числа заполнения нейтронов для орбитd 3/2,d 1/2,s 1/2 иf 7/2 для основного состояния изотопов кремния и сравниваются с предсказаниями обоблочечной модели.
