Abstract
In these proceedings we briefly discuss preliminary results from 138Ba(d, α) and 138Ba(p, t) reactions performed using the Q3D magentic spectrometer at the Maier-Leibnitz- Laboratorium (MLL) tandem accelerator facility in Garching, Germany. Our results aim to provide useful spectroscopic information for the calculation of the 136Xe →136 Ba double beta decay matrix elements.
Highlights
The existence of massive neutrinos open up the possibility of observing neutrinoless double beta (0νββ) decays, which are lepton number violating (LNV) processes that would affirm the Majorana nature of neutrinos
The nuclear matrix elements (NMEs) for 0νββ decays are calculated as a sum of virtual transitions over states up to high excitations in the intermediate odd-odd nucleus [1, 6]
The global optical model potential (OMP) parameters best suited for the Distorted Wave Born Approximation (DWBA) analysis were deduced from 138Ba(d, d) elastic scattering data for the incoming channel [22] and from McFadden and Satchler [23] for the outgoing (α +136 Cs) channel
