Shell-model analysis of the 136Xe double beta decay nuclear matrix elements.
Neutrinoless double beta decay, if observed, could distinguish whether the neutrino is a Dirac or a Majorana particle, and it could be used to determine the absolute scale of the neutrino masses. 136Xe is one of the most promising candidates for observing this rare event. However, until recently there were no positive results for the allowed and less rare two-neutrino double beta decay mode. Th...
متن کاملThe Majorana neutrino masses, neutrinoless double beta decay and nuclear matrix elements
The effective Majorana neutrino mass mββ is evaluated by using the latest results of neutrino oscillation experiments. The problems of the neutrino mass spectrum, absolute mass scale of neutrinos and the effect of CP phases are addressed. A connection to the next generation of the neutrinoless double beta decay (0νββ-decay) experiments is discussed. The calculations are performed for Ge, Mo, Xe...
متن کاملn-p Interaction Effects on the Double Beta Decay Nuclear Matrix Elements for Medium Mass Nuclei
The quality of HFB wave functions are tested by comparing the theoretically calculated results with the available experimental data for a number of spectroscopic properties like yrast spectra, reduced B(E2) transition probabilities, quadrupole moments and g-factors for the nuclei involved in 2ν ββ decay. It is observed that the np interactions vis-à-vis the deformations of the intrinsic ground ...
متن کاملDouble beta decay versus cosmology: Majorana CP phases and nuclear matrix elements
We discuss the relation between the absolute neutrino mass scale, the effective mass measured in neutrinoless double beta decay, and the Majorana CP phases. Emphasis is placed on estimating the upper bound on the nuclear matrix element entering calculations of the double beta decay half life. Consequently, one of the Majorana CP phases can be constrained when combining the claimed evidence for ...
