Hypersatellite and satellite transitions in xenon atoms

Decay of double-K-shell-vacancy states in xenon atoms, created in the decay of ${}_{}{}^{131}{}_{}{}^{}\mathrm{Cs}$, was investigated. The measurements were performed with a pair of germanium detectors, a fast-slow coincidence system, and a three-parameter pulse-height analyzer. In the analysis of the two-dimensional ${\mathit{E}}_1$-${\mathit{E}}_2$ spectrum, improved least-squares routines were applied. The following results were derived: the probability of creation of a double K-shell vacancy per ${}_{}{}^{131}{}_{}{}^{}\mathrm{Cs}$ decay, ${\mathit{P}}_{\mathit{K}\mathit{K}}$=(1.48±0.35)×${10}^{\mathrm{-}5}$; the hypersatellite energy shifts ${\mathrm{\Delta }}^{\mathit{h}}$(Kα)=(653±20) eV, ${\mathrm{\Delta }}^{\mathit{h}}$(K${\mathrm{\beta }}_1$)=(834±39) eV, and ${\mathrm{\Delta }}^{\mathit{h}}$(K${\mathrm{\beta }}_2$)=(903±81) eV; the average values of the satellite energy shifts due to the presence of an ${\mathit{L}}_3$- or ${\mathit{L}}_2$-shell spectator vacancy ${\mathrm{\Delta }}^{\mathit{s}}$(Kα${\mathit{L}}^{\mathrm{-}1}$)=(80±15) eV, ${\mathrm{\Delta }}^{\mathit{s}}$(K${\mathrm{\beta }}_1$${\mathit{L}}^{\mathrm{-}1}$)=(169±34) eV, and ${\mathrm{\Delta }}^{\mathit{s}}$(K${\mathrm{\beta }}_2$${\mathit{L}}^{\mathrm{-}1}$)=(261±81) eV; the intensity ratios of the hypersatellite transitions, I(K${\mathrm{\alpha }}_2^{\mathit{h}}$)/I(K${\mathrm{\alpha }}_1^{\mathit{h}}$)=0.94±0.18, I(K${\mathrm{\beta }}_1^{\mathit{h}}$)/I(K${\mathrm{\alpha }}_1^{\mathit{h}}$)=0.36±0.06, and I(K${\mathrm{\beta }}_2^{\mathit{h}}$)/ I(K${\mathrm{\alpha }}_1^{\mathit{h}}$)=0.09±0.04; the intensity ratios of the satellite transitions I(K${\mathrm{\alpha }}_2$${\mathit{L}}^{\mathrm{-}1}$)/I(K${\mathrm{\alpha }}_1$${\mathit{L}}^{\mathrm{-}1}$)=0.44±0.10 and 0.44±0.09 for an ${\mathit{L}}_3$ and ${\mathit{L}}_2$ spectator vacancy, respectively; and the intensity ratios of some other satellite transitions.
