Magnetic moment of the first excited state of Mo 99

We have measured the g factor of the 5/2/sup +/ first-excited state of /sup 99/Mo. We obtained for this state, which has an excitation energy of 98 keV and a mean life of 24.5 ..mu..s, a value g = - 0.310 +- 0.002. This result is consistent with the g factor observed for the d/sub 5/2/ level in neighboring odd neutron nuclei, and in approximate agreement with theoretical calculations.
