Abstract
The reactions Ar,α2pMo and Ar,4pMo 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 and . A singles angular distribution experiment using the reaction Cl,3pMo has been performed at 120 MeV beam energy to measure spin assignments in and to calibrate the DCO analysis for both nuclei. Reduced transition probabilities for more than 60 transitions in have been reduced. The extensive data set is incorporated in a detailed comparison between the two nuclei and, for , with predictions from shell model calculations within a restricted π(),π(),ν(), and ν() configuration space and with different residual interaction parameters. The electromagnetic properties of the negative parity states of are well reproduced by the calculations while the positive parity states show hints of seniority mixing at intermediate spins.
