Angular distributions for deuteron-/sup 16/O elastic scattering and the / sup 16/O(d, p)/sup 17/O reaction leading to levels with E/sub x = 0.0, 0.87 and 5.08 MeV were measured at energies of 25.4, 36.0 and 63.2 MeV. The elastic deuteron data were fit with a standard spin one optical model potential to obtain parameters for use in a DWBA analysis of the (d, p) data. The potential found in the search is shown to be consistert with other data taken in the range from 25 to 82 MeV. In addition to this deuteron optical potential, an adiabatic deuteron potential, which includes the effects of deuteron breakup, was used in the DWBA analysis. The neutron form factor was selected independent of the width of any state. The mean square radius, a single particle property, is used to find the well parameters and it determines the width of the single particle state. The spectroscopic factors obtained for the ground and first excited states are between 0.8 and 1.0 and are consistent with a large single particle parentage for these states and lower energy data. The width extracted from the DWBA analysis of the 5.08 MeV unbound state was 20% less than that obtained from elastic neutron scattering to the same state, possibly pointing up some difficulties with DWBA procedures commonly used. The adiabatic deuteron potential yields spectroscopic factors that are energy independert to 20% and gives satisfactory calculated angular distribution shapes for angles less than 40 deg . The conventional deuteron potertial gives less satisfactory calculated shapes with the consequent introduction of some ambiguity in the derived spectroscopic factors. (auth)
