We have continued our studies of the p-spectrum of [sup 14]C using a germanium detector doped with [sup 14]C. There is a feature in the [beta]-spectrum 17 keV below the endpoint which could be explained by the hypothesis that there is a heavy neutrino emitted in the [beta]-decay of [sup 14]C with a mass of 17[plus minus]1 keV and an emission probability of 1.26[plus minus]0.25%. However, we also have performed a high statistics measurement of the inner bremsstrahlung spectrum of [sup 55]Fe and find no indication of the emission of a 17-keV neutrino. We conclude that the origin of the kink'' that has been observed in some recent beta spectral measurements is not a neutrino.
