Robust ab initio predictions for dimensionless ratios of E2 and radius observables. I. Electric quadrupole moments and deformation
Mark A. Caprio, Pieter Maris, Patrick J. Fasano
Converged results for E2 observables are notoriously challenging to obtain in ab initio no-core configuration interaction (NCCI) approaches. Matrix elements of the E2 operator are…

Benchmark neutrinoless double-beta decay matrix elements in a light nucleus
R. A. M. Basili, J. M. Yao, J. Engel +4
We compute nuclear matrix elements of neutrinoless double-beta decay mediated by light Majorana-neutrino exchange in the A = 6 system. The goal is to benchmark two many-body approa…
