Level Studies of 93Mo via (p, nγ) Reaction

The excited states of 93Mo have been investigated via 93Nb(p, nγ)93Mo reaction with the proton beam energies from 2.7-4.3 MeV. The angular distributions have been used to assign the spins and the multipole mixing ratios using statistical theory for compound nuclear reactions. The ambiguity in the spin values for the 2181.3, 2247.3 and 2539.3 keV levels have been removed. The multipole mixing ratios eight γ-transitions have been newly measured. The lifetimes of the levels at 2539.3 and 2642.0 keV have been measured for the first time using Doppler shift attenuation method. The experimental results are compared with the existing theoretical models. (author)
