First search for $2\epsilon$ and $\epsilon {\beta }^{+}$ decay of ${}^{174}$Hf

Abstract

The first ever search for $2\epsilon$ and $\epsilon {\beta }^{+}$ decay of ${}^{174}$Hf was realized using a high-pure sample of hafnium (with mass 179.8 g) and the ultra low-background HPGe-detector system located 225 m underground. After 75 days of data taking no indication of the double beta decay transitions could be detected but lower limits for the half-lives of the different channels and modes of the decays were set on the level of $\lim T_{1/2}\sim 10^{16}-10^{18}$ a.
