Precise energy values of X-ray spin doublet levels

Abstract

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.

Structure of high-resolution Kβ1,3 x-ray emission spectra for the elements from Ca to Ge

“…The Kβ 1,3 spin doublet values observed and calculated in this work are presented in Table IV and Fig. 6, together with other observed values [4,5,10] and the recommended values based on the experimental results of Campbell and Papp [42], the values obtained from a refinement of the modified Moseley plot method by Misra et al [43], and Pham et al [15]. The Lorentzian model was used for an analytic representation of Kβ x-ray lines [4,14], and the results of the fitting analyses are shown in Fig.…”

An iterative method for obtaining accurate atomic inner shell binding energies

“…1d), then it is found that the points lying on the limbs of the unsymmetrical parabola do not now transform into a straight line parallel to the Z-axis. Instead, a plot comprising two inclined straight lines is generally obtained [6] with the vertex of the modified Moseley plot transforming into a point R which lies on the line joining the points of discontinuity P and Q of the above mentioned two inclined straight lines (Fig. 1d).…”
