Abstract

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