The low-lying, low-spin levels of Se76 were studied with the (n,n′γ) reaction. Gamma-ray excitation function measurements were performed at incident neutron energies from 2.0 to 3.5 MeV, and γ-ray angular distributions were measured at neutron energies of 2.4, 3.0, and 3.7 MeV. From these measurements, level spins, level lifetimes, branching ratios, and multipole mixing ratios were determined. We established the 02+ band, which supports the shape coexistence in Se76 predicted by large-scale shell model calculations and the interacting boson model.
