Ab initio theory of light nuclei and NN interaction of JISP type

Abstract

I discuss ab initio studies of light nuclei in large-scale No-Core Shell Model calculations on supercomputers with extrapolations to the infinite model space (No-Core Full Configuration approach). The convergence at the end of p shell and beginning of the sd shell can be achieved if only reasonable soft enough NN interactions are used. In particular, good predictions are obtained with a realistic JISP16 NN interaction obtained in J-matrix inverse scattering approach and fitted to reproduce light nuclei observables without three-nucleon forces. We discuss some recent results obtained with this NN interaction.
