|Title:||Theory Of Electron-hydrogen-atom Collisions In The Presence Of A Laser Field|
Lins De Barros H.G.P.
|Abstract:||Expressions for the scattering amplitude of multiphoton processes occurring during the collision of electrons with a hydrogen atom in the presence of an electromagnetic field have been obtained in several approximations: the momentum translation, the space translation, and the Keldysh approximation for the bound-electron wave function. We also propose a perturbation approach based on the space-translation approximation to treat the hydrogen-atom bound states. Our results show that it is of fundamental importance to consider the modifications of bound states due to the presence of the field. © 1978 The American Physical Society.|
