Neutrinoless double-electron capture
Abstract
Direct determination of the neutrino mass is at the present time one of the most important aims of experimental
and theoretical research in nuclear and particle physics. A possible way of detection is through neutrinoless
double-electron capture, 0νECEC. This process can only occur when the energy of the initial state matches
precisely that of the final state. We present here a calculation of prefactors (PFs) and nuclear matrix elements
(NMEs) within the framework of the microscopic interacting boson model (IBM-2) for 124Xe, 152Gd, 156Dy, 164Er,
and 180W. From the PF and NME we calculate the expected half-lives and obtain results that are of the same order
as those of 0νβ+β+ decay, but considerably longer than those of 0νβ−β− decay.
