Abstract
Internal bremsstrahlung in the electron capture decay of 55Fe has been studied to investigate the possible existence of neutrinos in the mass range of 15 to 45 keV. At the 95.5 % confidence level, our limit for the fraction of emitted neutrinos in the mass range of 15 to 45 keV ranges from < 1.6% in the lower mass region to < 0. 1 % in the higher mass region.
