Nuclear Structure with Discrete Non-Orthogonal Shell-Model : new frontiers

preprint2022arXivOpen access

Abstract

We present developments and applications for the diagonalization of shell-model hamiltonians in a discrete non-orthogonal basis (DNO-SM). The method, and its actual numerical implementation CARINA, based on mean-field and beyond-mean field techniques has already been applied in previous studies and is focused on basis states selection optimization. The method is benchmarked against a full set of sdsd shell exact diagonalizations, and is applied for the first time to the heavy deformed 254^{254}No nucleus.
