Abstract
The emission of rays from neutron-bound and neutron-unbound states in , populated in the reaction, has been investigated. Charged particles and radiation were detected with arrays of annular silicon and Clover-type high-purity Germanium detectors, respectively. Utilizing and coincidences, the level scheme was greatly enhanced with 102 new transitions and 43 new states. It agrees well with shell model calculations for excitation energies below MeV. From coincidence data, a new method for the determination of spins of discrete levels is proposed. The method exploits the suppression of high-angular momentum neutron emission from levels with high spins populated in the reaction above the neutron separation energy. Spins for almost all levels below 2 MeV (and for a few levels above) have been determined with this method.
