Studying the Ground States of 6, 7, 9, 11Li Nuclei by Feynman Continual Integrals Method

Abstract

The energy and the square of the wave function modulus for the ground state of ^{6, 7, 11}Li nuclei are calculated using Feynman continual integrals in the model of the interaction between a nuclear core and external nucleons. The obtained energy values are in good agreement with the experimental data. The appearance of deuteron and triton clusters was demonstrated in the structure of ⁶Li and ⁷Li nuclei, respectively. Calculations in the shell model of a deformed nucleus are also performed for ^{7, 9, 11}Li nuclei. Both models help explain the strong deformation of the ⁷Li nucleus.
