EFFECTS OF THE INTERNAL STRUCTURE OF THE ALPHA-PARTICLE IN THE 3-BODY PROBLEM OF D-ALPHA SCATTERING

The methods of dimensional reduction of the six-body problem in the adiabatic representation are used to construct three-body differential dynamical equations with energy-dependent interactions describing elastic scattering and disintegration in the He-4 + (np) system. The energy dependence of the interactions is generated by the internal structure of He-4. In the framework of a model based on modified Faddeev equations the contributions of five-body resonances Li-5(gs) and He-5(gs) and of the six-body resonance Li-6(1+) to the amplitudes of elastic scattering and deuteron disintegration are studied.
