“…However, since the total multiple-excitation cross section, which is used in the present work for the determination of the sum of single-excitation cross sections, is obtained from the data of Murakami et at. [13], these two measurements cannot be considered truly independent. The present experimental cross sections deviate considerably from our previous experimental cross sections [14] and from the Bd cross section of Lindle et al [15].…”

The photoionization of krypton 4p, 4s, and 3d subshells has been studied theoretically from the 4p threshold and experimentally from the 3d threshold up to a photon energy of 260 eV. In converting the measured count rates of the 4p, 4s, and 3d main photoelectron lines into partial cross sections, we have used recent photoion yield measurements to estimate the contribution of multiple-excitation processes to the total photoabsorption cross section. Theoretical partial cross sections and angular asymmetry parameters have been calculated using the multichannel Dirac-Fock method. Eighteen leading single-excitation channels related to the 4p, 4s, 3d, and 3p hole configurations of the final ionic state were included. Relaxation was taken into account by using separately optimized initialand final-state orbitals and by including all the resulting overlap integrals in the transition amplitudes. The relaxation eKect was found to depend strongly on the photon energy in the near-threshold regions. For the 3d subshell the relaxation reduces the 3d cross section by 35 -40% at the maximum, whereas it is less significant for the 4p and 4s cross sections.PACS number(s): 32.80.Fb

Dedicated to the 100th anniversary of Professor A. JucysFollowing the creation of inner-shell vacancy in an atom, the cascade of radiative and nonradiative transitions takes place. It can be analysed employing the final charge distribution of ions, the electron and characteristic emission spectra. The development of the experimental and theoretical investigation of cascades is shortly reviewed. The main attention is paid to the description of a cascade using the global characteristics of spectra, especially in the cases of transitions between close-lying and overlapping configurations. Some applications of the global characteristics method are given.

“…Going from Ar 2p to Kr 3d ionization, the DAD BR increases to about 25-30% [60,43,45,47,48,32]. In sharp contrast to the lighter Ne and Ar atoms, the relaxation is found to proceed almost exclusively by cascade decay [50,54,55].…”

Abstract. Electron correlation is an essential driver of a variety of relaxation processes in excited atomic and molecular systems. These are phenomena which often lead to autoionization typically involving two-electron transitions, such as the well-known Auger effect. However, electron correlation can give rise also to higherorder processes characterized by multi-electron transitions. Basic examples include simultaneous two-electron emission upon recombination of an inner-shell vacancy (double Auger decay) or collective decay of two holes with emission of a single electron. First reports of this class of processes date back to the 1960's, but their investigation intensified only recently with the advent of free-electron lasers. High fluxes of high-energy photons induce multiple excitation or ionization of a system on the femtosecond timescale and under such conditions the importance of multielectron processes increases significantly. We present an overview of experimental and theoretical works on selected multi-electron relaxation phenomena in systems of different complexity, going from double Auger decay in atoms and small molecules to collective interatomic autoionization processes in nanoscale samples.
