Description
Symmetries of the IBFFM will be discussed and Spectroscopic Amplitudes
(SA) in the Interacting Boson Fermion Fermion Model (IBFFM) are
necessary for the computation of 0\nu\beta\beta0νββ decays but also for
cross-sections of heavy-ion reactions, in particular, Double Charge
Exchange reactions for the NUMEN collaboration, if one does not want to
use the closure limit. We present for the first time: the formalism and
operators to compute in a general case the spectroscopic amplitudes in the
scheme IBFFM from an even-even to odd-odd nuclei, in a way suited to be
used in reaction code, i.e., extracting the contribution of each orbital.
The one-body transition densities for 116Cd → 116In and 116In →
116Sn [1] are part of the experimental program of the NUMEN experiment,
which aims to find constraints on Neutrinoless double beta decay matrix
elements.
