This book presents a comprehensive overview of nuclear physics field. The emphasis was on the No-Core Shell Model Calculations for some Light Nuclei. It contains the latest knowledge of the subject based on a thorough review of the literature over the past 15 years. Large-scale shell model calculations have been performed to study the low-lying energy levels for light and light halo nuclei. The calculations have been performed using the recent shell model code. The theoretical results and calculations for both no-core with three restrictions and with closed core taken at 4He with ckpot...
