Nuclear matrix elements for double-{\beta} decay
Abstract
Background: Direct determination of the neutrino mass through double- decay is at the present time one of the most important areas of experimental and theoretical research in nuclear and particle physics. Purpose: We calculate nuclear matrix elements for the extraction of the average neutrino mass in neutrinoless double- decay. Methods: The microscopic interacting boson model (IBM-2) is used. Results: Nuclear matrix elements in the closure approximation are calculated for Ca, Ge, Se, Zr, Mo, Pd, Cd, Sn, Te, Te, Nd, Nd, Sm, Gd, and Pt decay. Conclusions: Realistic predictions for the expected half-lives in neutrinoless double- decay with light and heavy neutrino exchange in terms of neutrino masses are made and limits are set from current experiments.
