Ab initio no core shell model
TLDR
In this paper, a non-perturbative ab initio no core shell model (NCSM) was proposed to solve the properties of nuclei exactly for arbitrary nucleon-nucleon (N N ) and N N + ǫ − three-N n interactions with exact preservation of all symmetries.About:

Status and future of nuclear matrix elements for neutrinoless double-beta decay: a review.

TL;DR: It is demonstrated that a proper treatment of the coupling to the n-10Be continuum is successful in explaining the parity-inverted ground state in 11 be, and the A=4 scattering results are compared to earlier ab initio calculations.
