KL-LLL (‘monopole ionizations’); and KLe–LL or Ke–L (‘high-energy satellites’).
From Table 5 it is possible to estimate the energies of transition for various pairs of
states, even though the ‘state’ energies are stricly speaking configurational averages.
Figure 1 shows (vertical lines) the estimated values of these transition energies, su-
perimposed on the experimental spectrum. It is noteworthy that, even if the vertical
lines are not actually coincident with the peak positions, the assignment of the peaks
for various processes is substantially in accord with that made by Moddeman et al
[21] on the basis of the experimental data.
