The isovector 0{sup +} to 0{sup {minus}} transition in the {sup 16}O(p,n){sup 16}F (g.s.) reaction was studied at 79 MeV. Differential cross sections were extracted for the transitions to the low-lying complex of 0{sup {minus}}, 1{sup {minus}}, 2{sup {minus}}, and 3{sup {minus}} states in {sup 16}F at 12 laboratory angles from 0.3{degree} to 63{degree} which correspond to momentum transfers from 0.21 to 2.0 fm{sup {minus}1}. An energy resolution of 140 keV (FWHM) was achieved which was sufficient to separate the yields for each of these four states. Distorted-wave-impulse-approximation (DWIA) calculations were performed and compared with the extracted cross sections for these four transitions. The DWIA calculations with the effective interaction of Franey and Love provide a good description of the experimental measurements for the 0{sup {minus}} transition at low momentum transfer, but overestimate the data at larger momentum transfer. The experimental results for the 1{sup {minus}}, 2{sup {minus}}, and 3{sup {minus}} transitions are described reasonably well by the DWIA calculations. {copyright} {ital 1997} {ital The American Physical Society}
