The reactions [sup 58]Ni([sup 36]Ar,[alpha]2[ital p])[sup 88]Mo and [sup 58]Ni([sup 36]Ar,4[ital p])[sup 90]Mo 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 [sup 88]Mo and [sup 90]Mo. A singles angular distribution experiment using the reaction [sup 58]Ni([sup 35]Cl,3[ital p])[sup 90]Mo has been performed at 120 MeV beam energy to measure spin assignments in [sup 90]Mo and to calibrate the DCO analysis for both nuclei. Reduced transition probabilities for more than 60 transitions in [sup 88,90]Mo have been reduced. The extensive data set is incorporated in a detailed comparison between the two nuclei and, for [sup 90]Mo, with predictions from shell model calculations within a restricted [pi]([ital p][sub 1/2]),[pi]([ital g][sub 9/2]),[nu]([ital p][sub 1/2]), and [nu]([ital g][sub 9/2]) configuration space and with different residual interaction parameters. The electromagnetic properties of the negative parity states of [sup 90]Mo are well reproduced by the calculations while the positive parity states show hints of seniority mixing at intermediate spins.
