Effects of deuteron breakup and nucleon-transfer reactions on d+^{11}B elastic scattering

Abstract

A set of experimental data consisting of angular distributions of d+^{11}B elastic and inelastic scattering and (d,t) reaction obtained at deuteron energy of 14.5 MeV as well as data sets for (d,p) (E_d = 21.5 MeV), (d,n) (E_d = 15.4 MeV) and (d,^3He) (E_d = 11.8 MeV) nucleon transfer reactions were analysed using the continuum-discretized coupled-channel (CDCC) and coupled-reaction channel (CRC) methods. It was found that at forward scattering angles the elastic scattering data are well described by parameter-free CDCC calculations which include breakup of the deuteron, but at more backward angles virtual effects due to target excitation and neutron-transfer reactions play an important role. The strongest effects are due to the excitation of ^{11}B and the neutron pickup reaction, reflecting their large cross sections. The effects induced by proton-transfer reactions are found to be negligible.
