Abstract
The properties of high-spin states in have been studied with the reaction. In-beam measurements with Ge(Li) and intrinsic Ge detectors of coincidences, -ray angular distributions, pulsed-beam timing, and perturbed angular distributions with an applied magnetic field were made to determine a decay scheme, level energies, -ray multipolarities, spin-parity assignments, an isomeric lifetime, and a factor. High-spin states up to were identified as either proton excitations of the () nucleus coupled to the ground state or neutron excitations of coupled to the ground state of . Lifetime and -factor measurements of the 2117-keV isomer, which yielded values of nsec and , respectively, strongly support a configuration for this level.
