|Title:||Nuclear many-body Continuum States and their Boundary Conditions in a Collective-Coordinate Representation|
Resonant and scattering states are calculated in the framework of nuclear many-body physics with microscopic interactions. A collective-coordinate representation is developed in order to express the boundary conditions for the asymptotic behaviour of the relative distance between the fragments. The boundary conditions are implemented in the Schrödinger many-body equation resulting in a modified eigenvalue problem. The advantage of this method is that it does not require the separation of the relative motion in the many-body states. 8Be and 5He are chosen as sample cases. Elastic scattering phase-shifts and resonance parameters in the low energy regime are calculated. The validity of the method is confirmed by comparison to other approaches that use phenomenological interactions. Finally, the first results in Fermionic Molecular Dynamics with a realistic interaction are presented.
