Direct high-precision measurement of the mass difference of ${}^{77}$As-${}^{77}$Se related to neutrino mass determination

Z. Ge, T. Eronen, M. Ramalho +20

The first direct determination of the ground-state-to-ground-state ${\beta }^{-}$-decay $Q$-value of ${}^{77}$As to ${}^{77}$Se was performed by measuring their atomic mass difference utili…
