    • Abstract

       

      The structure of nuclear transition matrix elements (NTMEs) required for the study of neutrinoless double-$\beta$ decay within light Majorana neutrino mass mechanism is disassembled in the PHFB model. The NTMEs are calculated using a set of HFB intrinsic wave functions, the reliability of which has been previously established by obtaining an overall agreement between the theoretically calculated spectroscopic properties and the available experimental data. Presently, we study the role of short-range correlations, radial evolution of NTMEs and deformation effects due to quadrupolar correlations. In addition, limits on effective light neutrino mass $\langle m_{\nu} \rangle$ are extracted from the observed limits on half-lives $T_{1/2}^{0\nu}$ of neutrinoless double-$\beta$ decay.
