Abstract

The reactions Ni58(36Ar,α2p)88Mo and Ni58(36Ar,4p)90Mo at 149 and 140 MeV beam energies have been used to carry out Doppler shift attenuation and recoil distance lifetime measurements and to determine DCO ratios in Mo88 and Mo90. A singles angular distribution experiment using the reaction Ni58(35Cl,3p)90Mo has been performed at 120 MeV beam energy to measure spin assignments in Mo90 and to calibrate the DCO analysis for both nuclei. Reduced transition probabilities for more than 60 transitions in Mo88,90 have been reduced. The extensive data set is incorporated in a detailed comparison between the two nuclei and, for Mo90, with predictions from shell model calculations within a restricted π(p1/2),π(g9/2),ν(p1/2), and ν(g9/2) configuration space and with different residual interaction parameters. The electromagnetic properties of the negative parity states of Mo90 are well reproduced by the calculations while the positive parity states show hints of seniority mixing at intermediate spins.
