Résumé

The doubly magic 132Sn region is interesting for many reasons. It offers the important information for the astrophysical processes model calculation, can gives the opportunity to take out the empirical N-N interactions as well as to test theoretical shell model description of nuclear structure in this region. The CW5082 interaction of the shell model code OXBASH has originally derived from the 208Pb region by using recent
experimental information of the 132Sn region. Then, this interaction has undergone the other modifications by different authors such as them S. Saha (SMN and SMPN interactions). We have developed by the new modifications of CW5082 interaction, at the calculations of the excited energies and the reduced probabilities B(E2) with A=135-136 Sn isotopes, in the shell model. The gotten results show a remarkable improvement in the predictive power when we compared them with the available
experimental results, and contrast well with the calculated results with the SMN and SMPN interactions.
