摘要：
Total and differential cross sections for and are measured. Values for the model-independent neutral-current couplings of the electron are found to be gV=-0.107±0.035(stat)±0.028(syst) and gA=-0.514±0.023(stat) ±0.028(syst). The electroweak mixing parameter sin2W is determined to be 0.195±0.018(stat)±0.013(syst). Limits are set for the charge radius and magnetic moment of the neutrino as (r2)<0.24×10-32 cm2 and f0.85×10-9 Bohr magnetons respectively. © 1990 The American Physical Society.
