Abstract

The low-lying structure of Sn112 has been studied by use of the (n,n'γ) reaction. Excitation functions and angular distributions of γ rays have been used to characterize the decays of the excited levels, and level lifetimes have been measured with the Doppler-shift attenuation method. A γγ coincidence experiment has also been performed to confirm γ-ray placements. Low-lying 1, 2(),3, and 5 states are suggested as members of a heterogeneous quadrupole-octupole quintuplet. Their excitation energies and decay properties are consistent with a structure formed by the coupling of the lowest quadrupole 21+ and octupole 31 excitations.
