Scattering Of 6He On α-Particle: Microscopic Guidance For Orthogonalizing Pseudopotentials

Section: Nuclei and nuclear reactions
Language: English

Abstract: Within a microscopic two-cluster model, we discuss the influence of the Pauli exclusion principle on the scattering of 6He on α-particle. The structure of the Pauli-forbidden and the Pauliallowed states is analyzed in detail. The influence of the Pauli-allowed states with eigenvalues other than unity on the kinetic energy of the relative motion of 6He and α-particle results in the effective interaction between these nuclei. This effect can be simulated to some extent with finite values of orthogonalizing pseudopotential strength. We estimate the strength and the range of such interaction within a microscopic model and provide a guidance for choosing the parameters of the orthogonalizing pseudopotential.

Key words: microscopic cluster model, Pauli exclusion principle, resonating group method.
