A Cu Ka And Cu Kb Lines Without Focusing Optics And B The Same With The 1. introduction. precision measurements of the wavelengths, energies, and spectral structures of x ray line complexes are needed for many purposes. our group at nist uses such data to certify lattice parameters of standard reference materials (primarily [ 1 – 3 ]) which are used to calibrate powder diffractometers. The intensity of a k line is given approximately by the formula i k = c i (v v k) n where i is the electron beam current, (c is a constant,) and v k is the excitation potential of the k line (as given earlier by v k = 12.398 [kv Å] λ ). the exponent n is approximately 1.5, but drops towards 1.0 when v > 2v k. Cu kβ is the second line in the copper emission spectrum and is accessible by replacing the mirror optics of a standard copper x ray source. cu kβ is not traditionally used for scxrd experiments, since its raw intensity is only around 1 8 of the commonly used cu kα and is typically removed by monochromatization (thompson et al., 2009). Ka line of cu. the estimated total flux of the 8.05 kev photons was equal to 5.9 9 1010 ph s in 4p sr. perfor mance boost of the source caused by x ray optics relied on the significant increase in the cu ka photon flux on both, the sample (4.7 9 106 ph s) and the detector (3.4 9 103 ph s). a spectral brightness of 1.4 9 107 ph s mm2 mrad2.

High accuracy mcdhf cu kα and cu kβ diagram spectra and major satellites are presented. spectral eigenvalues reach a theoretical expansion convergence of 0.03 ev or 0.00025%, with gauge and amplitude convergence to 0.7% for cu kα diagram spectra. dominant theoretical spectral eigenvalues are shown to be within 0.032 ev of experimental data. Mm, (horizontal) slit widths of 1.0 mm (focus side) and 10 mm (sample side) for both spectra, and (vertical) slit heights of 0.4 mm for the cu ko. radiation and 0.8 mm for the cu kp radiation. iii. atomic structure calculations a. introduction we have considered transitions involving up to two vacancy states, of the forms 1s np and 1s3l— np33.
