الوصف الكامل (Full Abstract)
Abstract:
Unrestricted shell model calculations in the lower fp-shell region for the nuclei 46Ti, 46Cr and 46V have been performed for the isovector T = 1 positive parity states using the shell model code OXBASH for Windows by employing the effective interactions GXPF1, FPD6 and KB3G. The level schemes and transition strengths B(E2; ?) are compared with the recently available experimental data. A very good agreement were obtained for all nuclei.
1. INTRODUCTION
The nuclear shell model has been very successful in our understanding of nuclear structure: once a suitable effective interaction is found, the shell model can predict various observables accurately and systematically. For light nuclei, there are several “standard” effective interactions such as the Cohen-Kurath [1] and the USD [2] interactions for the p and sd shells, respectively. On the other hand, in the next major shell, i.e., in the fp-shell, there were also “standard” interactions such as FPD6 [3] and GXPF1 [4]. The spectroscopy of nuclei, in the fp-shell region, has been well described within the shell model framework. Extensive shell model calculations have been performed in this mass region, using several model spaces and two-body interactions, the most remarkable work of Brown and co-workers [5–11]. Because of the quite importance of the fp-shell for variety of problems in nuclear structure, such as electron capture in supernova explosions. In this letter we report the shell model calculations in the lower fp-shell region for the nuclei 46Ti, 46Cr and 46V, to test the the ability of the present effective interactions in reproducing the experiment in this mass region.
