Abstract: Shell model calculations with BCS theory were performed to study the first exited states and the reduced transition probabilities for the A= 78 chain of isobars by employing the MSDI as a residual interaction between two quasiparticles, in the pure configurations and the configuration mixing for all allowed states on the full valence space . The core is taken at for all nuclei under study and the results of our theoretical calculations are compared with the most recent available experimental data. It was found that the shell model using BCS theory and MSDI is still one of the most suitable models to carry out, such as calculations, and taking configuration mixing into consideration, enhances considerably, the results, more than the case of pure configurations when comparison with experimental data, and we found success for MSDI as a residual interaction even when the valance nucleons is large.
Keywords: configuration mixing, modified shell model, quasiparticle, transition probability, occupation amplitude.
