Structure of the 6He nucleus in the three-particle model

The properties of the 6 He nucleus were investigated in a three-particle approximation (a alpha-particle cluster plus two neutrons) on the basis of the variational approach by using a Gaussian basis. For nn and nα interactions, potentials that make it possible to describe S -wave phase shifts for el...

description The properties of the 6 He nucleus were investigated in a three-particle approximation (a alpha-particle cluster plus two neutrons) on the basis of the variational approach by using a Gaussian basis. For nn and nα interactions, potentials that make it possible to describe S -wave phase shifts for elastic scattering and, simultaneously, to reproduce faithfully the energy and the size of the 6 He nucleus were proposed. Characteristic structural features of this nucleus that are manifested in the density distributions, elastic form factor, pair correlation functions, and momentum distributions of particles constituting the 6 He nucleus in the three-particle model were revealed.
