Abstract

Low-energy excited states of Ra-210 and Ra-208 were investigated at the Wright Nuclear Structure Laboratory of Yale University. Fusion evaporation recoils were selected using the gas-filled spectrometer, SASSYER. Delayed gamma-rays, following isomeric decays, were detected at the focal plane of SASSYER with,a small array,of HPGe detectors. Transitions following the proposed J(pi) = 8(+) isomers were. observed, and the half-lives measured. The experiments are discussed and results compared to expectations from the seniority scheme.
