Abstract
The low-lying structure of has been studied by use of the () 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 coincidence experiment has also been performed to confirm γ-ray placements. Low-lying , , and 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 and octupole excitations.
