Boehm, F

In this paper we report on a search for neutrino oscillations performed at the nuclear power reactor in Goesgen (Switzerland). The energy spectra of the electron antineutrinos emerging from the reactor core have been measured at distances of L/sub 1/ = 37.9 m (experiment 1), L/sub 2/ = 45.9 m (experiment 2) and L/sub 3/ = 64.7 m (experiment 3). The measured spectra are analyzed in terms of a two-neutrnio oscillation model. Two analyses are presented: (A) the first is based exclusively on a comparison of the measured spectra obtained at the three distances L/sub j/. This analysis is essentially independent of any external assumptions concerning the reactor antineutrino spectrum, the detection cross section and the detector efficiency; (B) the second analysis includes the reactor antineutrino spectrum as derived from independent ..beta..-spectroscopic measurements. This procedure increases our sensitivity to the oscillation parameters. 29 refs., 13 figs., 5 tabs.
