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