多頻道α-α交互作用力

Abstract

We have obtained the alpha- alpha interaction for the coupled channels in which the internal structure of the alpha particles is approximately represented by a two-state system.In this model, the alpha-alpha interaction is represented by a 3*3 matrix. By using an unitary transformation, we obtain an exact expression for the phase shift in terms of the potential parameters which is determined from the two-body scattering data.
