dc.description.abstractTo investigate the natural linewidths of Cu Kα1,2 diagram lines, the spectra of these lines were recorded in detail using an anti-parallel double-crystal X-ray spectrometer. The values obtained for the measured Cu Kα1 and Kα2 natural linewidths are 2.264(18) eV and 2.534(73) eV, respectively. The contribution of the Coster-Kronig (CK) transition for the Kα2 linewidth is found to be approximately 0.27 eV. Theoretical values 2.1454 eV for the Kα1 line and 2.1292 eV for the Kα2 line were calculated, using the GRASP and FAC codes. A detailed study of the same spectra using Si and Ge crystals and several Bragg surfaces was performed. In addition, the spectral measurements of Cu Kα3,4 satellite lines were made, and information on the energy values, FWHMs, and intensity ratios of these satellite lines was obtained from multiple-peak fitting analyses.en
