OSTI ID:5546897
Differential cross sections and vector-analyzing power were measured at incident deuteron energies of 15 MeV and 17 MeV for the /sup 16/O(d,d)/sup 16/O, /sup 16/O(d,d')/sup 16/O(3/sup -/) and /sup 16/O(d,p)/sup 17/O reactions and at 16 MeV for the /sup 18/O(d,d)/sup 18/O, /sup 18/O(d,d')/sup 18/O(2/sup +/) and /sup 18/O(d,p/sub 0/)/sup 19/O reactions. The data are compared to the predictions of the DWBA and CCBA theories. The spectroscopic factors of With's shell-model calculations were used in the CCBA calculations. The fits to the data for the /sup 16/O(d,p)/sup 17/O reaction indicate that the first (1/2/sup +/) and the fifth (3/2/sup +/) excited states are formed exclusively by one-step transfer, the ground state (5/2/sup +/), fourth (3/2/sup -/+ and eighth (7/2/sup -/) excited states are produced mainly by one-step processes and the second (1/2/sup -/) and third (5/2/sup -/) excited states require both one- and two-step processes. The ground state of /sup 19/O(5/2/sup +/) is formed mainly by a one-step transfer with a small contribution from the two-step process. The magnitude of the previously determined spectroscopic factors for the two-step transfer appears to have been overestimated.
