Intensified and Asymmetric Barrier Penetration of Nuclear Slabs in Time-Dependent Hartree-Fock Approximation

摘要

The effects of intensified and asymmetric barrier penetration by complex particles exhibiting intrinsic structure are investigated in the framework of the time-dependent mean-field theory using an effective one-dimensional layer geometry and a simplified Skyrme nucleon-nucleon effective interaction. The transmission coefficient D(E) has been investigated as a function of incident energy E anU layer thickness. The appearance of discontinuities in D(E) is discussed in detail. It is argued that quantum corrections to the standard TDHF picture as well as the transition to three dimensions possibly smearing out the discontinuities should not alter the qualitative results. In nearly all considered cases the penetrability is really substantially intensified and the asymmetry effect manifests itself as predicted earlier using a simple quasideuteron model.
