Abstract

The properties of the five-nucleon system is investigated with a multi-configuration resonating-group method. The model space adopted is spanned by p + α, d + 3He and deuteron pseudo-inelastic configurations. The results indicate that, with no adjustable parameters, the main characteristics of the p + α and d + 3He differential scattering and reaction angular distributions can be reasonably well explained. Calculated total reaction cross sections in the p + α channel are found to be generally higher than experimental values, while the opposite is true in the d + 3He channel. These latter findings are correlated with the observation that the general magnitudes of the calculated differential scattering cross sections in the p + α and d + 3He channels are, respectively, smaller and larger than the measured results. Defects in the present model are also discussed, and a way to correct these defects is proposed.
