Nuclear Structure and β− Decay of A = 90 Isobars

In the aim of estimating the β− decay properties of few nuclei in the A ~ 90 region with few hole protons and particle neutrons in addition to 100Sn doubly magic core, some spectroscopic calculations have been realized. The using interaction is derived from snet one taking into account the three body interaction effect in the studied mass region, and using recent single particle and hole energies. The calculations are carried out in the framework of the nuclear shell model by means of NuShellX@MSU code. The getting results have been compared to the available experimental data.
