Abstract: Studies on electron antineutrino-electron elastic scattering were performedusing a 200-kg CsITl scintillating crystal detector array at the Kuo-ShengNuclear Power Plant in Taiwan. The measured cross section of Rexp = 1.00 +-0.32statxRSM is consistent with the Standard Model expectation and thecorresponding weak mixing angle derived is sin2T = 0.24 +- 0.05 stat. Theresults are consistent with a destructive interference effect between neutraland charged-currents in this process. Limits on neutrino magnetic moment ofmunu e < 2.0 x 10^-10 mu B at 90% confidence level and on electronantineutrino charge radius of r^2 < 0.12 +- 2.07x10^-32 cm^2 were alsoderived.
