“…The theoretical half-life of DBD+ of 78 Kr decay to the g.s. of 78 Se spreads over a wide range [178][179][180][181][182][183]: 10 24 -10 29 yr for the 2ν2β + case and 10 21 -10 25 yr for the 2ν β + and 2ν2 cases. The first positive claim of 2νDBD+ of 78 Kr occurred in 2013 [168] using a low background proportional counter (LPC).…”

Status and Perspectives of 2ϵ, ϵβ+ and 2β+ Decays

2021

This paper reviews the main experimental techniques and the most significant results in the searches for the 2ϵ, ϵβ+ and 2β+ decay modes. Efforts related to the study of these decay modes are important, since they can potentially offer complementary information with respect to the cases of 2β− decays, which allow a better constraint of models for the nuclear structure calculations. Some positive results that have been claimed will be mentioned, and some new perspectives will be addressed shortly.

“…The half-life that is predicted in the literature for the DBD+ in 64 Zn to the g.s. of 64 Ni spreads over a range of [182,183]: 10 34 -10 36 yr for the 2ν β + case and 10 26 -10 27 yr for the 2ν2 case. The best limit for the transition 0ν β + (g.s.)…”
