The emission of gamma rays from neutron-bound and neutron-unbound states in Mo-95, populated in the Mo-94(d, p) reaction, has been investigated. Charged particles and gamma radiation were detected with arrays of annular silicon and Clover-type high-purity Germanium detectors, respectively. Utilizing p-gamma and p-gamma-gamma coincidences, the Mo-95 level scheme was greatly enhanced with 102 new transitions and 43 new states. It agrees well with shell model calculations for excitation energies below approximate to 2 MeV. From p-gamma 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 (d, p) reaction above the neutron separation energy. Spins for almost all Mo-95 levels below 2 MeV (and for a few levels above) have been determined with this method.
