M. Dorr et al., BORN-FLOQUET THEORY OF ELECTRON-ATOM COLLISIONS IN THE PRESENCE OF A LASER FIELD, Zeitschrift fur Physik. D, Atoms, molecules and clusters, 29(4), 1994, pp. 245-246
We present a theory of fast electron-atom collisions in the presence o
f a strong laser field, which treats the interaction of the laser fiel
d with both the projectile electron and the target atom in a fully non
-perturbative way. The theory is illustrated by considering the laser-
assisted ''elastic'' scattering of fast electrons by atomic hydrogen,
for non-resonant as well as resonant cases.
