Abstract

77Se has been investigated by the reaction74Ge(α,) at 14 MeV. Gamma singles spectra, gamma angular distributions and gamma-gamma coincidences have been taken. A level scheme has been established, spins and parities have been assigned. States of a rotational band on the 1/2 ground state, a rotational band on the 5/2 249.7 keV state and an anormal band have been identified.

Nuclear Reaction 74Ge(α,n γ)E α=14 MeV; measuredE γ ,I γ ,γ-γ-Coin.,γ-ang. distr.77Se deduced levels,J, π. Enriched target, Ge (Li).
