ELECTRON PARAMAGNETIC RESONANCE STUDY OF CRYSTAL LATTICE SILVER IN GALENA.

The authors studied the silver in galena by means of electron paramagnetic resonance (EPR) for the first time. The results show that there is a fine structure line of the Gauss type in the spectrum. It is demonstrated that crystal lattice silver occurs in galena. In addition, the authors explained why this line had been generated and computed the concentration of lattice silver by contrasting this line with the intensity of the fine structure line. A new method has been provided for studying the occurrence of lattice silver in galena or in other sulfides.
