Abstract

There has been significant progress in the ab initio approaches to the structure of light nuclei. One such method is the ab initio no-core shell model (NCSM). Starting from realistic two- and three-nucleon interactions this method can predict low-lying levels in p-shell nuclei. In this contribution, we present a brief overview of the NCSM with examples of recent applications. We highlight our study of the parity inversion in ¹¹Be, for which calculations were performed in basis spaces up to 9ℏΩ (dimensions reaching 7×10⁸). We also present our latest results for the p-shell nuclei using the Tucson-Melbourne TM^′ three-nucleon interaction with several proposed parameter sets.
