We discuss the studies of light nuclei in ab initio No-core Full Configuration ap-proach based on extrapolations to the infinite model space of large-scale No-core Shell Model calculations on supercomputers. 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 the current status of this NN interaction and its recent development.
Ключевые слова: realistic nucleon-nucleon interaction, the shell model without an inert core, the spectra of light nuclei, the formalism of J-matrix method.
