Abstract
Neutron single-particle states in the neutron-rich nucleus Si, which is located beside the shell breaking nucleus Mg, were investigated through their isobaric analog resonances. The excitation function for Si elastic scattering was measured around in the laboratory frame by the thick target inverse kinematics method with a Si beam around 5 MeV/nucleon and a thick polyethylene target. Eight resonances were successfully observed. Angular momenta and proton and total widths of the resonances were assigned using -matrix analysis. With the help of information of the decay study, six isobaric analog resonances were identified. Spectroscopic factors and spin-parities of the corresponding parent states in Si are presented.
