The Results of Search for the Neutrino Magnetic Moment in GEMMA Experiment

The result of the neutrino magnetic moment measurement at the Kalinin Nuclear Power Plant (KNPP) with GEMMA spectrometer is presented. The antineutrino-electron scattering is investigated. A high-purity germanium detectorwith a mass of 1.5 kg placed at a distance of 13.9m from the 3 GW(th) reactor core is exposed to the antineutrino flux of 2.7 x 10(13) 1/cm(2)/s. The recoil electron spectra taken in 18134 and 4487 hours for the reactor ON and OFF periods are compared. The upper limit for the neutrino magnetic moment mu(v) < 2.9 x 10(-11) mu(B) at 90% C.L. is derived from the data processing.
