Abstract

The fluorescent CKα - spectra of ultra dispersed diamonds (UDD), separated into fractions by size, were obtained. The distinction between the spectra are more pronounced in the short-wave region. A quantum-chemical calculation of the C136 diamond cluster was performed using the MNDO method. Hydrogen atoms were placed on the broken bonds of the edge carbon atoms. According to the results of the calculation, the theoretical CKα- spectra of the cluster's surface and volume were simulated. In the theoretical and experimental spectra the same tendencies are reflected if the surface carbon atoms are linked to oxygen groups.
