Shell model structure at 100Sn the nuclides 98Ag, 103In, and 104Sn, 105Sn

The neutron deficient nuclei98Ag,104Sn withT z 2 and103In,105Sn T z 5 2 were studied in beam following the reaction of 250 MeV58Ni 50Cr. Neutron and charged particle p, amp; 945; gated amp; 947; amp; 947; coincidence spectra were used to identify these nuclei, which are populated with yields between 0.05 and 2 of the total residue cross section, and to determine their level schemes. In a comprehensive shell model study various approaches for the residual interaction were used to describe these newly and several previously studied neutron deficient nuclei. As a result predictions for the neutron single particle energies for100Sn are obtained and used to discuss the next generation of experiment
