Abstract
The 17 keV neutrino, proposed by Simpson in 1985 [1], may be an artifa ct of the data analysis which includes an oversimplified response func tion for monoenergetic electrons. This function was assumed to contain a backscatter fraction that is independent of energy. It is demonstra ted that, when artificial ''data'' are simulated for an external-sourc e beta decay experiment with a realistic response function containing an energy-dependent backscatter fraction, but are analyzed with a resp onse function containing a constant backscatter fraction, an artifact roughly equivalent to a 17 keV neutrino emerges.
