$\text{Ab initio}$ calculation of the calorimetric electron capture spectrum of ${}^{163}$Holmium: Intra-atomic decay into bound-states

M. Braß, C. Enss, L. Gastaldo +1

The determination of the electron neutrino mass by electron capture in ${}^{163}$Ho relies on a precise understanding of the deexcitation of a core hole after an electron capture eve…
