States inMo93to 5 MeV byMo92(d,pγ)Mo93Coincidence Measurements

Abstract

Measurements of the decay from excited states in ${}_{}{}^{93}{}_{}{}^{}\mathrm{Mo}$ following sub-Coulomb stripping have been made using the reaction ${}_{}{}^{92}{}_{}{}^{}\mathrm{Mo}(d,p\gamma ){}_{}{}^{93}{}_{}{}^{}\mathrm{Mo}$ at an incident deuteron energy of 6.0 MeV. Both particle and $\gamma$-ray singles measurements were made using Si(Li) and Ge(Li) detectors. Proton-$\gamma$ coincidence spectra produced by 43 gates on proton groups associated with ${}_{}{}^{93}{}_{}{}^{}\mathrm{Mo}$ were accumulated by means of a two-parameter computer sorting program and yielded 24 levels with energies up to 5 MeV in excitation. A total in excess of 50 $\gamma$ rays was assigned to the deexcitation of levels in ${}_{}{}^{93}{}_{}{}^{}\mathrm{Mo}$. Branching ratios at ${\theta }_L=90\mathrm{}°$ are given for the transitions from the excited states along with a decay scheme observed following the ($d,p$) reaction.
