Abstract
High-energy rays from the reaction (,) have been observed decaying from states between 32 and 39 MeV in . A narrow unexpectedly strong line, corresponding to decay to a state at 14.8±0.1 MeV in , was observed with an angular distribution suggesting a strong component. Structure in the excitation function of this transition favors a resonant rather than direct-capture mechanism. Comparisons with SU(3)- and shell-model calculations suggest a giant quadrupole excitation built on the state in .
