摘要：

The result of the neutrino magnetic moment (NMM) measurement at the Kalinin Nuclear Power Plant (KNPP) with GEMMA spectrometer is presented. The antineutrino-electron scattering is investigated. A high-purity germanium (HPGe) detector with a mass of 1. 5 kg placed at a distance of 13. 9 m from the 3 GWth reactor core is exposed to the antineutrino flux of 2. 7 × 1013 cm-2s-1. The recoil electron spectra taken in 18134 and 4487 h for the reactor ON and OFF periods are compared. The upper limit for the NMM μν < 2. 9 × 10-11 μB at 90% C. L. is derived from the data processing. © 2013 Pleiades Publishing, Ltd.
