Ab initio no-core shell model study of ²⁰Ne

Ab initio theories of nuclear physics focus on describing various nuclear systems starting from the free nucleon nucleon interactions among the nucleons. The no-core-shell model (NCSM) is one such approach which is very successful in describing different nuclear properties in the lighter mass region. Motivated from the encouraging results of the previous works, we have done comprehensive study the Ne isotopic chain from neutron shell closure N = 8 to N = 14 for several nuclear properties. In this paper, we have presented our study on ²⁰Ne isotope using two realistic NN interactions, inside non-local out-side Yukawa (INOY) and optimized next-to leading order (N²LO_opt). The E2 moments and transition strengths obtained from these two interactions are not in good agreement with the experimental data. Thus, we need even higher N_max calculations for better agreement with the experimental values
