L- andM-shell-electron shake processes following1sphotoionization in argon and krypton

The photoinduced $K\ensuremath{\alpha}$ and $K\ensuremath{\beta}$ x-ray spectra of argon and krypton were measured by means of high-resolution crystal diffractometry. Ar $K{\ensuremath{\alpha}}_{1,2}{L}^{(1)}$ and $K{\ensuremath{\beta}}_{1,3}{M}^{(1,2)}$ and Kr $K{\ensuremath{\alpha}}_{1}{L}^{(1)}$ and $K{\ensuremath{\beta}}_{2}{M}^{(1,2)}$ satellites were observed and resolved from the corresponding diagram lines. From the satellite to parent diagram line yield ratios, the probabilities for producing via shake processes ${K}^{(1)}{L}^{(1)}$ and ${K}^{(1)}{M}^{(1)}$ double-hole states were deduced. The results are compared to the few other existing experimental data and to theoretical sudden approximation predictions. The latter are found to underestimate somewhat the experimental values.
