INNER-SHELL PHOTOABSORPTION OF Kr, Rb and Xe ATOMS. Ph.V. Demekhin*, I.D. Petrov*, N.V. Demekhina*, V.L. Sukhorukov*, A. Kodre#=87, I. Arcon=87=A7, R.

To describe the near-edge fine structure the single- and double-electron excitation/ionization cross sections were calculated using the relativistic Pauli-Fock approximation. The monopole rearrangement of electron shells and the effect of the polarization of the atomic core by an exciting electron were taken into account.
