Abstract

The characteristic X-ray intensities of Ag-L_α, L_β1, L_β2 and L_γ1 are measured in electron-impact ionization at energy of 10 keV. The emission angle in this work ranges from 0° to 20° at interval of 5°. The angular dependence of L X-ray intensity ratios has been investigated for L_α / L_β1, L_β2 / L_β1 and L_γ1 / L_β1. It is found from the experimental results that the emissions of L_β1, L_β2 and L_γ1 X-rays are spatially isotropic, while the L_α X-rays exhibit anisotropic emission. Consequently, the alignment behavior of vacancy states is discussed with thorough analysis of vacancy transfer process.
