We perform a detailed study of the process [ital e][sup +][ital e][sup [minus]][r arrow][gamma][nu][sub [ital l]][bar [nu]][sub [ital l]] and its sensitivity to anomalous gauge boson couplings of the [gamma][ital WW] vertex. We concentrate on CERN LEP II energies, [radical][ital s] =200 GeV, and energies appropriate to the proposed Next Linear Collider (NLC), a high energy [ital e][sup +][ital e][sup [minus]] collider, with center of mass energies [radical][ital s] =500 and 1 TeV. At 200 GeV, the process offers, at best, a consistency check of other processes being considered at LEP 200. At 500 GeV, the parameters [kappa][sub [gamma]] and [lambda][sub [gamma]] can be measured to about [plus minus]0.05 and [plus minus]0.1, respectively, at 95% C.L. while at 1 TeV they can be measured to about [plus minus]0.02. At the high luminosities anticipated at high energy linear colliders precision measurements are likely to be limited by systematic rather than statistical errors.
