Mo98(p, d)Mo97reaction and core coupling inMo97andNb97

The ${}_{}{}^{98}{}_{}{}^{}\mathrm{Mo}(p, d){}_{}{}^{97}{}_{}{}^{}\mathrm{Mo}$ reaction has been used at a bombarding energy of 38.6 MeV to populate neutron hole states of ${}_{}{}^{97}{}_{}{}^{}\mathrm{Mo}$. Excitation energies and angular distributions were measured for levels up to 4.5 MeV in excitation. A distorted-wave-Born-approximation analysis was used to make $l$ assignments and to obtain spectroscopic factors. Three distinct groups of weakly excited levels, one corresponding to $l=4\mathrm{}$ and two corresponding to $l=1\mathrm{}$, were observed lying above 2.7 MeV excitation. A hole-core-coupling model is used to predict the properties of ${}_{}{}^{97}{}_{}{}^{}\mathrm{Mo}$ and ${}_{}{}^{97}{}_{}{}^{}\mathrm{Nb}$ and good agreement with the experiment is obtained.
