Search for heavy neutrinos in the $\beta$-spectrum of $^{63}Ni$
The $\beta$-spectrum of $^{63}$Ni has been measured with highprecision in order to search for effects of heavy neutrinos.For assumed neutrino masses in the range 4 to $ 30 \,$keV,upper limits of $ 10^{-3} $ or less are reported for themixing probability.
