A MICROSCOPIC TWO-CLUSTER MODEL OF PROCESSES IN 6Li

Structure of bound and resonance states and dynamics of different processes in Li-6 are investigated within a microscopic two-cluster model. The model is an algebraic version of the resonating group method which correctly treats the Pauli principle and makes use of the oscillator basis to expand a wave function of a two-cluster system. Within this model the nucleus Li-6 is considered as two-cluster alpha + d system. Dynamics of the two-cluster system is totally governed by a semi-realistic nucleon-nucleon potential. We study interaction of Li-6 with electrons and photons. Form factors of elastic scattering of electron are determined for two nucleon-nucleon potentials. We also study the density distribution of protons and neutrons in Li-6. We demonstrate that the model used correctly reproduces form factors for the ground state of Li-6. Our results are compatible with results of other microscopic models. The capture reaction alpha + d = Li-6 + gamma are investigated in detail. The astrophysical S-factor of the reaction is obtained at low-energy region.
