Total and differential cross sections for {nu}{sub {mu}}{ital e}{r arrow}{nu}{sub {mu}}{ital e} and {bar {nu}}{sub {mu}}{ital e}{r arrow}{bar {nu}}{sub {mu}}{ital e} are measured. Values for the model-independent neutral-current couplings of the electron are found to be {ital g}{sub {ital V}}={minus}0.107{plus minus}0.035(stat){plus minus}0.028(syst) and {ital g}{sub {ital A}}={minus}0.514{plus minus}0.023(stat){plus minus}0.028(syst). The electroweak mixing parameter sin{sup 2}{theta}{sub {ital W}} is determined to be 0.195{plus minus}0.018(stat){plus minus}0.013(syst). Limits are set for the charge radius and magnetic moment of the neutrino as ({l angle}{ital r}{sup 2}{r angle}){lt}0.24{times}10{sup {minus}32} cm{sup 2} and {ital f}{sub {mu}}{lt}0.85{times}10{sup {minus}9} Bohr magnetons, respectively.
