“…The Auger cascade spectra were mostly studied for Ar [13,29,30,[72][73][74][75][76][77]; also several works were devoted to Kr [31,73], Xe [31,32,78], Al [26], Ni [79], and Eu [66]. Because the X-ray transitions accompanying the cascade decay of inner-shell vacancies are less probable than the Auger transitions, the cascade affected emission spectra are less investigated, the results are mainly obtained for inert gases [27,33,[80][81][82][83][84] as well as for Fe [37], Ag [80], and Pb, Th, U [85]. During the last years some angle resolved studies of the Auger cascades following photoexcitation from an inner shell were performed for Ar, Kr, and Xe [31,[86][87][88][89].…”

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.

“…effectively the final-state potential is screened by the resonantly excited electron. Unfortunately, so far such an experimental study has never been made, except for the xray-emission study of 3p core-hole decay, which confirms the theoretical prediction of the partial decay width ratios of the 3p core-level ionized states [11].…”

The 3p '~5s ' resonant excitation energy and decay width of Kr atoms are calculated by an ab initio Green's-function method. The dipolar relaxation energy shift of the 3p ' -+Ss' resonantly excited state of Kr atoms is predominantly due to the 3p '5s'~3d 25s'sf super-Coster-Krouig (sCK) spectator decay process. The calculated excitation energies are overestimated by about 1. 0 eV. The decay widths for 3p /2~5 s ' and 3p3/2~5 s ' resonantly excited states are 2.08 and 1.88 eV, respectively. They are larger than the decay widths of the 3p &/& and 3p3/g core-level ionized states. The increase of the decay width is a result of the decrease of 3p '5s '~3 d~5s 's f sCK spectator decay aud the increase of 3p '5s' -+3d '4s(p) '5s'cp(d) CK spectator decay. The changes of the (s)CK decay rates are due to the screening of the final two-hole-state potential by the resonantly excited 5s electron.PACS number(s): 32.30. Rj, 32.70.Jz, 32.80.0z, 32.80.Hd

“…The spectrum shows a continuous intensity distribution over the lower photon energy region of 490 to 525 eV and one broad prominent peak (about 10 eV FWHM) at 531 eV photon energy. Verkhovtseva and Pogrebnjak (1980) interpret this prominent peak to be of the same character as the one in the corresponding XPS spectrum and that the unusually broad profile on the lower photon energy side is due to the breakdown of the one-electron picture of a 4p hole by a g c K 4p-l*4d-'~f process.…”

“…Recently Verkhovtseva and Pogrebnjak (1980) have measured the 3d-1 + 4p-' XES spectrum of Xe in order to study the strong dynamical effect of a '4p' hole by x-ray emission spectroscopy. The initial hole state of the 3d-' + 4p-' emission transition is a doublet (spin-orbit splitting of 3d levels is 12.6 eV and level width is 0.5 eV (Svensson et a1 1976)).…”

The 3d-' + 4p-' x-ray emission spectrum of Xe has been calculated from first principles by diagrammatic many-body theory within the framework of a free-atom calculation. The agreement of the theoretical spectrum with experiment is good. The spectrum is entirely dominated by the strong dynamical effects of a final 4p hole. The one-electron picture of a 4p hole breaks down by a strong dynamical giant Coster-Kronig 4 p -'~4 d -~m , E f process.
