Generalized time-dependent generator coordinate method for small- and large-amplitude collective motion

An implementation of the generalized time-dependent generator coordinated method (TD-GCM) is developed, that can be applied to dynamics small- and large-amplitude collective motion atomic nuclei. Both states weight functions GCM correlated wave function depend on time. The initial are obtained as solutions deformation-constrained self-consistent mean-field equations, evolved in time by standard equations nuclear density functional theory (TD-DFT). TD-DFT trajectories used a generally nonorthogonal overcomplete basis which TD-GCM expanded. weights, expressed terms function, obey (integral) equation. In this explorative paper, excitation energies spreading width giant resonances, induced fission. necessity including pairing correlations demonstrated latter example.
