| Résumé : |
The aim of our work is constant to the study of the neutron-rich tin isotopes region.
This study is based on the determination of excited energies and the reduced probabilities of
electric transition B(E2) for the nuclei with two and three valence nucleons of 134, 135Sn, 134,
135
Sb and 134, 135Te.
The calculations are made in the framework of the shell model using the nuclear structure
OXBASH code. We have used as starting point the existing interactions in the literature of tin
region: KH5082, CW5082 with Z50N82 model space and of Plomb region: KHHE.
We have modified these interactions to obtain KH5082R, KH5082N, KH208, SLN and
SLPN. These modifications are made to reproduce the experimental results. They take for
base, the experimental single particle energies, the two bodies matrix elements, and the tin
region model space . The results obtained are in agreement with those of the experiment with
regard to the energy spectra of the nuclei with two valence nucleons and present some
different in the case of three nucleons. The values of the effective charge (ep = 1.47e and
en=0.62e) reproduce the best experimental reduced probabilities of electric transition B(E2). |
