O. Mauron et al., L-shell shake processes resulting from 1s photoionization in elements 11 <= Z <= 17 - art. no. 062508, PHYS REV A, 6206(6), 2000, pp. 2508
The photoinduced K alpha x-ray spectra of elements between sodium and chlor
ine were measured by means of high-resolution crystal diffractometry. The K
alpha (1,2),L-(1) satellites were observed and resolved from the correspon
ding diagram lines. The probabilities for producing via shake processes (KL
(1))-L-(1) double-hole states were deduced from the satellite to parent dia
gram line yield ratios. The results are compared to theoretical sudden appr
oximation predictions. A satisfactory agreement is found except for sodium
and chlorine for which our experimental results are markedly underestimated
by the calculations.
