高电荷态离子入射Ta表面形成的靶原子的特征光谱线

The characteristic spectral lines induced by the impact of highly charged ion on Ta solid surface

报道了用动能一定而电荷态不同的40Arq+离子和动能不同的40Ar6+离子入射金属Ta表面,靶原子受激辐射发出的200-1000nm波段的特征光谱线的实验结果。实验结果表明:高电荷态离子所激发的靶原子的谱线强度与入射离子的电荷态密切相关,与靶原子的入射动能没有强的相关性。

The measurement of light spectrum with wavelength from 200nm to 1000nm emitted from solid surface of Ta which is excited by slow highly charged ions40Arq -Hand 40Ar6 + is reported. The result shows that the intensity of the characteristic spectral lines of the target atom is intimate relation with the charge state q of incident ions and hadn't strong correlation with the initial kinetic energy of the incident ions.
