The K-L vacancy transfer probability of 3d atoms such as Cr, Cu and Zn and their compounds have been measured using Indus - 2 synchrotron radiation. The emission of K X-ray photons in the elemental and compound targets are induced by 6.5 keV, 10 keV and 11 keV synchrotron radiation. The characteristic K X-ray photons are measured with a silicon drift detector spectrometer. By measuring K shell fluorescence yield and K X-ray intensity ratios, the K-L vacancy transfer probabilities have been determined and found that they depend on solid state effect.
