EXTENDED SHELL MODEL CALCULATION FOR EVEN N=82 ISOTONES WITH A REALISTIC EFFECTIVE INTERACTION

摘要

The shell model within the 2s1dOg(7/2)Oh(11/2) shell is applied to calculate nuclear structure properties of the even Z = 52-62, N = 82 isotones, The results are compared with experimental data and with the results of a quasiparticle random-phase approximation (QRPA) calculation. The interaction used in these calculations is a realistic two-body G-matrix interaction derived from modem meson-exchange potential models for the nucleon-nucleon interaction. For the shell model all the two-body matrix elements are renormalized by the (Q) over cap-box method whereas for the QRPA the effective interaction is defined by the G-matrix.
