Neutron transfer reactions to constrain matrix element for neutrino less double beta decay of ¹²⁴Sn

Neutrinoless double beta decay (NDBD) is expected to give the first direct measure of the effective neutrino mass. The uncertainty in the latter will be dominated by that in the relevant nuclear matrix element (NME). The present work is aimed to study neutron pickup and stripping transfer cross-sections on one of the 0ν2β-decay candidate ¹²⁴Sn and its daughter ¹²⁴Te. This nucleus is the focus of neutrino-less double beta decay study, at the upcoming underground India based Neutrino Observatory (INO). This information will be useful for constraining calculations of the nuclear matrix element for the 0ν2β-decay of ¹²⁴Sn
