Shell model based Coulomb excitation γ-ray intensity calculations in107Sn

In this work, we present recent shell model calculations, based on a realistic nucleon–nucleon interaction, for the light 107, 109Sn nuclei. By combining the calculations with the semi-classical Coulomb excitation code GOSIA, a set of γ-ray intensities has been generated. The calculated intensities are compared with the data from recent Coulomb excitation studies in inverse kinematics at the REX-ISOLDE facility with the nucleus 107Sn. The results are discussed in the context of the ordering of the single-particle orbits relative to 100Sn.
