Spectroscopy of \u3csup\u3e88\u3c/sup\u3eY by the (\u3cem\u3ep,dγ\u3c/em\u3e) Reaction

Abstract

Low-spin, high-excitation energy states in 88Y have been studied using the 89Y(p,dγ) reaction. For this experiment a 25 MeV proton beam was incident upon a monoisotopic 89Y target. A silicon telescope array was used to detect deuterons, and coincident γ rays were detected using a germanium clover array. Most of the known low-excitation-energy low-spin states populated strongly via the (p,d) reaction mechanism are confirmed. Two states are seen for the first time and seven new transitions, including one which bypasses the two low-lying isomeric states, are observed
