Resonance structure of 8Be with the two-cluster resonating group method
Abstract
A two-cluster microscopic model is applied to study elastic alpha-alpha scattering and resonance structure of 8Be. The model is an algebraic version of the Resonating Group Method, which makes use complete set of oscillator functions to expand wave function of two-cluster system. Interaction between clusters is determined by well-known semi-realistic nucleon-nucleon potentials of Hasegawa-Nagata, Minnesota and Volkov. Detail analysis of resonance wave functions is carried out in oscillator, coordinate and momentum spaces. Effects of the Pauli principle on wave functions of the 8Be continuous spectrum states are thoroughly studied.
