Study Of Low-Lying States In Mg-32

Proton inelastic scattering on the neutron-rich nucleus Mg-32 has been experimentally studied at E-lab = 46.5 MeV/nucleon in inverse kinematics. The energies of excited states in Mg-32 were obtained by measuring de-excitation gamma rays. Several new states were identified by gamma-gamma coincidence analysis. Their spins and parities were restricted and the deformation parameters beta(p,p)' were extracted from the measured angular distribution of the proton inelastic scattering. The present analysis favors 4(+) for the spin and parity of the 2321-keV state.
