摘　　要：依托兰州重离子加速器国家实验室,测量了不同动能的129Xe^(26+)离子与Ni表面作用产生的特征X射线谱,结果表明,3.0 MeV的Xe^(26+)不仅激发出了Ni的L_(α)、Xe的M_(αα)特征X射线,还激发出了Xe的L_(α)和L_(β)特征X射线。对Xe^(26+)与Ni作用时X射线的产生机制和产生Xe的L-X射线的动能阈值进行了初步分析。It was measured that the characteristic X-ray spectra produced by the impact of highly charged ions of 129Xe^(26+)with different kinetic energies on Ni surface in the National Laboratory of Heavy Ion Research Facility in Lanzhou.It was found that 3.0 MeVXe^(26+)could excite both the characteristic X-ray spectra of L_(α)of Ni and M_(αα)of Xe and the characteristic X-ray spectra of L_(α)andL_(β)of Xe.A preliminary analysis was made of the mechanism of X-ray excitation and the kinetic energy threshold of L X-ray of Xe forXe^(26+)exciting Ni emission.
