“…In order to calculate the screen ing parameters in the X-ray spectra of astatine, the energy levels given by Bearden and Burr [130] were used. The value of for the К level was esti mated as 6.494 [143]; values of о 2 for the S-^/2 terms of L^, M^, and levels are given as 2.5, 7.0, and 13.0, respectively [144]. The calculated values of and о f o r various spin doublets are summarized in Table 15 [145 to 148] .…”

The energy values of the individual members of those spin doublets of levels for certain atomic number ranges, for which only the experimentally obtained weighted averages of these energies were tabulated by Bearden and Burr (1967), have been calculated by using the screening parameters sigma 1 and sigma 2 previously reported by the authors. The energy values so obtained are further refined by the method of the modified Moseley plot. These refined energy values of the individual members of the spin doublets agree very well with the experimental electron spectroscopic energy values of Fuggle and Martensson (1980) and those of Cardona and Ley (1978) as corrected by Williams. The screening parameters sigma 1 and sigma 2 for a number of doublets of levels are reported for the first time.
