Three-particle structure of the halo nucleus 6Li

Abstract

The three-particle model for 6Li nucleus (α-cluster, and two halo nucleons p and n) is used to study the structure properties of this system within the variational method with Gaussian basis. The ground triplet (Jπ = 1+) and the excited singlet (Jπ = 0+) states of 6Li are studied. For this purpose, potentials of the np- and Nα-interaction are proposed to give description of the elastic S-phases at low energies simultaneously with correct values of the binding energy and the charge radius of 6Li nucleus. The density distributions, elastic form factors, pair correlation functions, clusterization coefficients, and momentum distributions of 6Li nucleus are studied.
