Abstract

Low-spin, high-excitation energy states in $^{88}$ Y have been studied using the $^{89}$ Y( $p, d γ$ ) reaction. For this experiment a 25 MeV proton beam was incident upon a monoisotopic $^{89}$ Y 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.
