| 英文摘要 | The X-ray spectra of Nb surface induced by Ar(q+) (q = 16,17) ions with the energy range from 10 to 20 keV/q were studied by the optical spectrum technology. The experimental results indicate that the multi-electron excitation occurred as a highly charged Ar(16+) ion was neutralized below the metal surface. The K shell electron of Ar(16+) was excited and then de-excited cascadly to emit K X-ray. The intensity of the X-ray emitted from K shell of the hollow Ar atom decreased with the increase of projectile kinetic energy. The intensity of the X-ray emitted from L shell of the target atom Nb increased with the increase of projectile kinetic energy. The X-ray yield of Ar(17+) is three magnitude orders larger than that of Ar(16+). |
