Аннотация

Structure of bound and resonance states and dynamics of different processes in 6Li 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 6Li is considered as two-cluster α + d system. Dynamics of the two-cluster
system is totally governed by a semi-realistic nucleon-nucleon potential. We study interaction of 6Li 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 6Li. We demonstrate that the model used correctly
reproduces form factors for the ground state of 6Li. Our results are compatible with results of other microscopic
models. The capture reaction α + d = 6Li + γ are investigated in detail. The astrophysical S-factor of the reaction is
obtained at low-energy region.
