Abstract : Studies of multiphoton ionization of atoms have revealed several unexpected characteristics. The confluence of the experimental evidence leads to the hypothesis that the basic character of the atomic response involves highly organized, coherent motions of entire atomic shells. The important regime, for which the radiative field strength E is greater than an atomic unit, can be viewed in approximate correspondence with the physics of fast atom-atom scattering. This physical picture provides a basis for the expectation that stimulation emission in the x-ray range can be produced by direct highly nonlinear coupling of ultraviolet radiation to atoms. Keywords: Ions, Multiphoton, Photons.
