Nuclear and weak interaction aspects of neutrinoless double beta decay: Recent results
The determination of the value of the light neutrino mass, as well as the determination of the nature of the neutrino, are two of the fundamental questions which motivate the experimental search of signals of neutrinoless double beta decay transitions. Here, we shall review some of the the essentials of the theory, based on both nuclear structure and elementary particle physics, relevant for the understanding of the problem.
Theoretical results on the double positron decay of 106Cd
Abstract Theoretical results for the double positron decay of 106 Cd are presented. The calculated values for the lateral single-beta-decay feeding patterns and electromagnetic transitions leading to states in 106 Cd and 106 Pd are discussed and compared to the data. The results on the double positron decay of 106 Cd are compared to new experimental limits. Based on the results of the present calculations, we report on the possibility of detecting the EC/EC or the β + /EC decay modes to final J π =0 + states using the improved sensitivity of the planned measurements.
