The Half-Life and the Nuclear Matrix Element of the $2νββ$ Decay in $^{76}Ge$

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/81485We apply the shell-model wave-functions of $^{76}Ge$ to calculate the nuclear matrix elements and the half-life of the $2νββ$ decay in $^{76}Ge$. Our result is comparable to the recent observed $2νββ$-decay half-life of $^{76}Ge$. Furthemore it provides the upper limit of the effective neutrino mass is about 0.4 eV from the recent experimental data of the $0νββ$-decay half-life.6 pagesNuclear TheoryThe Half-Life and the Nuclear Matrix Element of the $2νββ$ Decay in $^{76}Ge$text
