NONLINEAR INTERFERENCE EFFECTS OF LASER PHOTOIONIZATION OF ATOMS NEAR-THE-SURFACE

The theory is developed of electron transfers between atoms, which res onantly interact with the coherent radiation, and the surface of the m etal. The dependences have been established of spectral resonances of photoabsorption and surface photoionization upon the nonlinear interfe rence effects of the interaction between the discrete atom states and continuum formed by the quasicontinuous electron spectrum of the norma l metal. It has been shown that asymmetry of the resonant surface phot oionization spectrum manifest in the form, which is rather typical of the Fano autoionization resonance.
