Hasan, Zaid A. Mohamed Abstract: : in this paper, the OXBASH computer software has been used for apply the nuclear shell model to the sulfur isotope 34S in order to calculate the excitation energies and the reduced probability of electric quadruple transition B(E2) and by depending each of effective interactions w and hbusd that describe the interaction between a nucleon-nucleon in an sd space for the nucleus under study, which contains 18 nucleons in the model space and by considering the isotope of oxygen 16O as the closed core, our theoretical calculations have been compared with the experimental data available for this isotope and we have noted a good match with it.
