ИСТИНА

The advent of X-ray free electron lasers and fourth generation synchrotron radiation sources has given a new impetus to the development of atomic inner shell photoelectron spectroscopy. The complex electron spectra contain many lines due to the shake-up satellites. The shake-up mechanism can be described quantitively only in advanced theoretical models. Bearing in mind future experiments with new brilliant sources of the XUV radiation, we consider 3d-photoionization of Kr, centering on the photon energies from 80 eV to 200 eV and binding energies from 110 eV to 135 eV.
