Comparison of shell model results for even-even Se isotopes

A comprehensive set of shell model calculations for Se78-84 isotopes have been performed with recently derived interactions, namely JUN45 and jj44b for f(5/2)pg(9/2) space. To study the importance of the proton excitations across a Z = 28 shell, in this region mentioned by Cheal et al (2010 Phys. Rev. Lett. 104 252502), calculations for fpg(9/2) valence space using an fpg effective interaction with Ca-48 as the core, and imposing a truncation, have also been performed. Comparison of the calculations with experimental data show that the predicted results of the jj44b interaction are in good agreement with experimental data.
