- Аннотация: Effects due to the Pauli principle in low-energy d He-4 scattering are studied within the framework of the three-particle (n,p,alpha) model. A strong quantitative difference is discovered in the behavior of the d He-4 partial-wave amplitudes in even and odd waves. The main attention is devoted to effects associated with the Pauli principle in the 3P(J) partial-wave amplitudes, where "ghosts" are discovered, i.e., bound states of three particles forbidden by the Pauli principle. It is found that the P-wave d He-4 phase shifts are very sensitive to the type of the N-alpha interaction in the S wave and that the experimental data on these phase shifts are better described by an attractive potential than by a potential with a repulsive core. A new efficient method is also proposed for inclusion of the Coulomb interaction in the three-body problem, which is valid both below and above the three-particle threshold (in the three-particle elastic channel).
