摘要：

In this paper, K-shell X-ray spectra of nitrogen are measured by the interaction of Nq+ (q = 3, 5) ions with Al and Cu surfaces in the impact energy range of 25–100keV. K-shell X-ray yields per incident ion and then ionization cross sections are deduced from the measured K-X-ray spectra. It is found that both the yields and cross sections increase quickly with increasing impact energy, but have no apparent dependence on the target material and the charge state of the incident ion. The experimental results reveal that the incident Nq+ (q = 3, 5...
