Abstract
This project looks at the angular distributions of the differential cross sections and analyzing powers of a few low lying states of 56 Co in the reaction 58 Ni(p, 3 He) 56 Co at three different incident energies between 80 and 120 MeV. The measurements are compared with zero-range distorted-wave Born approximation (DWBA) calculations in which we assume a simple direct two-nucleon pickup process. Earlier inclusive (p, 3 He) reaction studies on similar targets were successfully treated in terms of a statistical pre-equilibrium multistep formalism, in which the final stage of the reaction involved a deuteron pickup, described by means of the DWBA. The analyzing power was shown to be rather sensitive to the contributions of the different order steps. However some features observed in the analyzing powers of these inclusive studies, though reproduced by the theory, are not fully understood. We therefore investigate the ability of the DWBA model to describe the (p, 3 He) pickup reaction to discrete states at different incident energies using a high resolution spectrometer.
Highlights
Many inclusive, pre-equilibrium reaction studies involving the emission of light 3He- and α-clusters following the interaction of medium energy polarized protons with target nuclei such as 59Co and 93Nb have been done in the past decade [1–4]
