摘要：

We calculate the He-3 + p scattering phase shifts for the S and P waves in a microscopic cluster model, in which the description of the He-3 wave function is extended from a simple (0s)(3) model to a three-body model. We employ two different nucleon-nucleon interactions, the Minnesota (MN) and AV8' potentials, to investigate the role of the d + 2p channel in the low-energy phase shifts. The role of the d + 2p channel in the P-wave phase shifts is very sensitive to the choice of the potential. The d + 2p channel is indispensable in reproducing the resonant phase shifts in the AV8' potential while it plays a minor role in the MN potential. On the contrary, the role of this channel in the S-wave nonresonant phase shifts is negligible in both potentials.
