Abstract
The isovector 0 to 0 transition in the OF (g.s.) reaction was studied at 79 MeV. Differential cross sections were extracted for the transitions to the low-lying complex of 0, 1, 2, and 3 states in F at 12 laboratory angles from 0.3 to 63 which correspond to momentum transfers from 0.21 to 2.0 fm. 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 transition at low momentum transfer, but overestimate the data at larger momentum transfer. The experimental results for the 1, 2, and 3 transitions are described reasonably well by the DWIA calculations.
