We have studied the {beta} spectrum of {sup 14}C using a germanium detector containing a crystal with {sup 14}C dissolved in it. We find a feature in the {beta} spectrum 17 keV below the end point which can 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}2 keV and an emission probability of (1.40{plus minus}0.45{plus minus}0.14)%.
