gammagamma decay as a probe of neutrinoless betabeta decay nuclear matrix elements

We study double gamma (γγ) decay nuclear matrix elements (NMEs) for a wide range of nuclei from titanium to xenon, and explore their relation to neutrinoless double-beta () NMEs. To favor the comparison, we focus on double-magnetic dipole transitions in the final ββ nuclei, in particular the γγ deca...
