Description
I report about the calculation of the nuclear matrix element involved in
neutrinoless double-β decay within the framework of the realistic shell
model.
Starting from a realistic nucleon-nucleon potential, the effective
shell-model Hamiltonian and 0νββ-decay operator are derived by way of the
many-body perturbation theory.
The contributions to the effective shell-model operator due to short-range
correlations and to the Pauli-principle violations are taken into account.
Attention will be focussed on some 0νββ-decay candidates with mass ranging
from A = 48 up to A = 136.
