Columns 2-5 of Table 10 give the energies (in keV) and relative intenslties of the K_a2, K_al, K^,', and K_a2‘ iines. Energies are given in boidface type, followed by intenslties normeiized to 100 for ihe K_al linę. The energies of'the K_a, and K_al lines are taken from the tables of Bearden.^ They have been rounded so that the uncertainty In the last digit is £5 unlts. The energies of the enmp!ex Kg_t' and K_a2’ lines are approximate weighted averages of the components, which can be separaled only by Instruments of high resolving power. For Zi93 the energies given are binding energy differences from Table 9.

The re!ative intenslties are adjusted experlmental values (and interpolations) from the tables of Salem, et al.*^ K_a2/K_al values appear to be uncertain by <1% at Z -20, increasing to «2% for high Z; K_fil’/K_al values appear to be uncertain by about 5% (sllghtly morę for Z<20); K_a3/K_as values are apparently accurate to »5%.

For Z&82 the K_at and components of K_ai' are given separately. The weak K_as component (not fncluded) is about 1.5% of the total K_a intensity for Pb (Z=B2) and B% for U (Z=92). The weak, forbldden component K_a3 (K-L_t) is likewise not given; its Intensity varies from 0.01% of K_fll for Nd (Z~60) to 0.2% for U (Z=92).

The last column of Table 10 glves the K-fluorescence yield, w_K. These data were calculated by Bambynek, et ai.^(3> from a semi-empiricai formula. Uncertainties In w_K vary from »25% for the lightest elements to «5% at Z=25 and wl-2% for the heaviest elements.
