激光辐照金靶的X光线谱标识

CLASSIFICATION OF X-RAYS PECTRA OF LASER-IRRADIATED GOLD TARGET

摘要: 在“神光”激光装置上,利用晶体谱仪测得Au在5.4～7.4Å的37条高分辨X光谱线。用Grant的MCDF程序计算理论波长,标识结果表明,绝人多数谱线来自类Co、类Ni、类Cu、类Zn、类Ga,类Ge和类As离子的4p→3d跃迁、此外,还观测到4s→3d电四极跃迁。

Abstract: By means of crystral spectrograph,we observed thirty-seven highly resolved x-ray spectral lines of A targets in the range of 5.4-7.4 angstroms on LF-12 Nd:glass laser facility.with the help of Grant's MC-DF program,most of spectral lines were identified to be the 4p-3d transition of Co-lik.Ni-like.Cu-like.Zn-like.Ga-like,As-like Au ion.Besides,five spectral lines were attributed to the quadrapote transitions of 4s-3d.
