Abstract: (HINDAWI)

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 detector with a mass of 1.5kg placed at a distance of 13.9m from the 3 G W t h reactor core is exposed to the antineutrino flux of 2 . 7 Oe 1 0 1 3 1/cm2/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 g g - < 2 . 9 Oe 1 0 -' 1 1 g g at 90% C.L. is derived from the data processing.
