Nuclear structure calculations in ${}^{20}$Ne with No-Core Configuration-Interaction model

Abstract

Negative parity states in ${}^{20}$Ne and Gamow-Teller strength distribution for the ground-state beta-decay of ${}^{20}$Na are calculated for the very first time using recently developed No-Core Configuration-Interaction model. The approach is based on multi-reference density functional theory involving isospin and angular-momentum projections. Advantages and shortcomings of the method are briefly discussed.
