Study of 16O(d, d)16O and 16O(d, p)17O using polarized deuterons

Abstract

Cross sections and vector and tensor analysing powers have been measured for 16O(d, d)16O, 16O(d, p0)17O and 16O(d, p1)17O* at bombarding energies of 9.3 and 13.3 MeV. For the elastic scattering, cross-section and vector-analysing-power data are reasonably well reproduced by optical-model calculations, but only rough qualitative agreement with the tensor analysing power is obtained. Some improvement in the agreement with the tensor-analysing-power data results if a tensor term TR is included in the optical potential. A degree of correspondence with the (d, p0) data at 9.3 MeV is achieved using DWBA calculations which take into account the D-state of the deuteron and the tensor potential TR. For Ed = 13.3 MeV, the general features of all the (d, p1) data except T21 (θ) can be realized using only an 1 · s spin dependence in the optical potentials. Non-stripping mechanisms appear to be operative in the (d, p) reactions, particularly at the lower energy. Show more
