摘要: The quadratic response formalism is used to derive a general expression for the Auger electron current in limit of high energies both photo- and electrons. decay initial core hole treated all orders rate. General formulas first second moments spectra are derived, simple results obtained limiting cases. We show that center gravity depends strongly on lifetime hole. competition between different processes can cause dramatic changes position shape peaks spectra. It also shown lead broadening photoelectron cannot be represented by Lorentzian convolution. discuss validity two-step model which assumed decoupled from creation
