NEUTRINO MAGNETIC MOMENT RESULTS AT THE KUO-SHENG NUCLEAR POWER PLANT.

A search of neutrino magnetic moment was carried out at the Kuo-Sheng Nuclear Power Station at a distance of 28 m from the 2.9 GW reactor core. With a high purity germanium detector of mass 1.06 kg surrounded by scintillating NaI(Tl) and CsI(Tl) crystals as anti-Compton detectors, a detection threshold of 5 keV and a background level of 1 kg-1kev-1day-1 at 12-60 keV were achieved. Based on 4712 and 1250 hours of Reactor ON and OFF data, respectively, the limits on the neutrino magnetic moment of $\mu_{\bar{\nu_{\rm e}}} < 1.3(1.0)\times 10^{-10}\ \mu_{\rm B}$ at 90(68)% confidence level were derived. Indirect bounds of the ${\bar{\nu_{\rm e}}}$ radiative lifetime of ${\rm m}^3_{\nu} \tau_{\nu} > 2.8(4.8)\times 10^{18}\ {\rm eV}^3{\rm s}$ can be inferred. The present status and future plans are discussed. [ABSTRACT FROM AUTHOR]
