Abstract
The three-nucleon system is studied within the multi-configuration resonating-group method. The model space is spanned byp+d,p+d′, and their associated pseudo-inelastic configurations. The results show that, at lower energies less than about 15 MeV, the calculatedp+d differential scattering and total reaction cross sections agree well with experiment, suggesting that the use of pseudo-inelastic configurations can yield an adequate description of deuteron direct-breakup processes. At higher energies, the agreement is less satisfactory, owing mainly to the adoption of a relatively small number of pseudo-inelastic configurations in our formulation. Thep+d inter-cluster interactions are found to be appreciably odd-evenL-dependent and are characteristically different in channel spinS=3/2 and 1/2states. Specific distortion effects of the deuteron cluster are also studied. For relative orbital angular momentumL=0, these effects turn out to be small in theS=3/2 state but are quite large in theS=1/2 state.

At energies higher than about 20 MeV, the 1C phase shifts are even slightly larger than the 3C phase shifts. This is a consequence of the fact that these exists in the 1C calculation a Pauli resonance (also referred to in the literature as an almost-forbidden state; see, e.g., Saito, S., Okai, S., Tamagaki, R., Yasuno, M.: Prog. Theor. Phys.50, 1561 (1973)) with a characteristic energy equal to about 50 MeV
