Differential cross-section and vector analyzing-power angular distributions were measured at {ital E}{sub {ital {rvec p}}} =58 MeV for the {sup 90}Zr({ital {rvec p}},{ital d}){sup 89}Zr reaction in the angular range from 6{degree} to 50{degree} and up to 10 MeV excitation energy, with 80 keV energy resolution. In addition to the transitions to low-lying states, the spectra display strong clusters of states from {ital E}{sub {ital x}}=3.5 to 7 MeV. The observed fine structure was used to define energy bins for which cross sections and analyzing powers were obtained. The latter allowed spin and parity assignments for deep-lying hole states. Spectroscopic factors were deduced from standard distorted-wave Born approximation calculations. From the vector analyzing-power measurements, it was shown that most of the strength observed above 3.5 MeV belongs to the 1{ital f}{sub 7/2} inner neutron hole orbital.
