Abstract

A three-body cluster 4He+t+n model is developed for 8Li using the method of hyperspherical harmonics with realistic cluster-cluster interactions fitted to experimental data. The model is used to calculate wave functions, spatial and matter densities of the ground state and the low lying excited state of 8Li. The model reproduces experimentally known properties of 8Li. Contrary to two-body models, our prediction for the radiative neutron capture on 7Li at low energies supports a lower cross section value.

    Citation Excerpt :

    The first version of the program, named RRCOE, was written by the author in 1987 and first used (though not published) in Ref. [1] at studying halo nuclei. It was used afterwards by the author and his collaborators, e.g., [2], as well as by other researchers. In the present version, considerable modifications and improvements are done.

    Citation Excerpt :

    The first microscopic model for 5H using the Generator Coordinate Method (GCM) was used in [15]. The key ingredient of the calculation, the NN potential, was based on semi-realistic Minnesota (MN) [16] and Mertelmeier and Hofmann [17] models. Resonance parameters were identified using the analytic continuation in a coupling constant (ACCC) method [18].
