Internal conversion electron study of excited states in $^{76}$As
ORAL
Abstract
Experiments on $^{76}$Ge and $^{76}$Se are revealing new information about double beta decay and giving better insight into whether or not the neutrino is Majorana particle. New data on intermediate nucleus $^{76}$As, which is virtually populated by double beta decay modes (2$\nu\beta\beta$, 0$\nu\beta\beta$), should lead to important constraints on the theoretical models that allow the determination of the neutrino mass. We carried out the $^{76}$Ge(p,n$\gamma$e$^{-}$)$^{76}$As reaction at 6.0 MeV at the ANU. Internal conversion coefficients have been obtained, giving better insight into the level structure of $^{76}$As. First results of the ongoing data analysis will be presented.
