Abstract
The validity of the Kroll-Watson approximation to treat electron-atom collisions in the presence of a laser field is discussed. Numerical ca lculations have been carried out using classical mechanics and a model potential to describe electron-helium scattering for conditions of ex perimental interest. The effect of an additional polarization term, ar ising from the interaction between the laser field and that due to the electron, is shown to be negligible.
