• The typical X-rays have been measured with a secondary-target system.
• The experimental setup provides us more choice to select incident energy.
• The discrepancy of the X-ray production ratios is determined experimentally.
The characteristic K-shell X-ray emission of Cu and L X-rays of Ta in photoionization has been measured at excitation energy of 15.9 keV. The differential X-ray production cross sections of Kα and Kβ for Cu and Lα, Lβ1, Lβ2, Lγ1 for Ta are derived at emission angles ranging from 100° to 150°. The ratio of Kβ and Kα X-ray production cross sections, Kβ/Kα, is calculated for Cu and it is found to be consistent with other work even at different incident energy. While the ratios of Lα/Lβ, Lα/Lγ1 and Lβ/Lγ1 for Ta are found to be different with other results at different excitation energy. The reasons giving rise to this discrepancy are clarified with thorough analysis.
