铜及玻璃靶激光等离子体X射线谱(LPX)的辨认

一、铜的LPX谱线的辨认 拍摄铜谱线的激光器件及摄谱条件与前文相同,图1、2是用KAP平晶拍摄到的紫铜球靶的x线谱及相应的黑度曲线。因为靶面功率密度约为10~(14)瓦/厘米]~2,尚不足以激励铜的K系谱线,此处8—13(?)的谱线均属于铜的L系跃迁(在图2中已用阿拉伯数字标出)。其中一些谱线的波长、相应的电子组态及光谱项列于表1。

IDENTIFICATION OF LASER-PRODUCED PLASMA X-RAY (LPX) SPECTRAL LINES IN Cu AND GLASS TARGETS

LPX spectral lines of copper and glass microball targeta have been photographed with the Kap eryatal spectrograph .Electron confinguration states and spectral terms at the transition of abort one hundred spectrum lines in the range of 8-13A for cu targest have been identified and nwe spectral lines that appeared have been found under the LPX eonditions.At the same time ,a set of spectral lines of the K-series of H-like and He-like ions of Si or Na and resonance lines of the thrace element Al in the glass shells have been identified in the plasma of the glass shell target.
