16O + 48Ca reaction at 56 MeV. I. Transitions to resolved levels

All direct reaction channels of significant strength (sigma > or = 50 μb) in the 16O + 48Ca reaction at E/sub lab/(16O) = 56 MeV were measured using a Δe - E time-of-flight telescope system. Excitation spectra with energy resolutions approx. = 200 keV full width at half maximum were obtained for outgoing ions /sup 11,12,13/B, /sup 12,13,14,15/C, /sup 14,15,16,17/N, and /sup 16,17,18,19/O. Angular distributions were obtained for the strongest transitions observed in inelastic scattering, the single-nucleon transfer reactions (16O, 15N) and 16O, 17O), the two-nucleon transfer reactions (16O, 14C), (16O, 14N), and (16O, 18O), the three-nucleon transfer reactions (16O, 13C), and the ''exotic'' transfers (16O, 16N) and (16O, 15C). Comparison of distorted-wave Born-approximation calculations for inelastic scattering, and for one- and two-nucleon transfer reactions to experiment suggest that reaction processes more complex than the one-step process are quite important in a majority of the transitions studied
