Radiative decay of autoionizing states in laser fields. I. General theory

摘要: A theory describing the radiative decay of an autoionizing state under strong pumping by a coherent field is developed. The systematically takes into account unperturbed continuum. problem at hand corresponds to case strongly coupled bound states decaying electron and photon continua with two also weakly each other. master equation time evolution atomic system derived, its exact solution arbitrary initial conditions given. effect on Fano profiles photoelectron spectra analyzed in detail. development examined. continuum changes significant way. characteristics are correlated dressed (with complex energies) system. structure as function parameters such spontaneous-emission rate laser intensity discussed
