摘要
应用自旋 -轨道劈裂不可分辨跃迁组理论对高离化 Au元素激光等离子体 0 .3～ 0 .4 nm范围的 X射线发射谱进行了分析。采用单温局域热动平衡近似 ,对实验谱进行理论模拟 。
The X-ray spectra emitted from laser-produced Au plasmas in the range of 0.3-0.4 nm are analyzed and interpreted by using the Spin-Orbit-Split Array model. The plasmas are created by using a beam of a frequency-tripled 1.05 μm Nd-glass laser focused onto a microdot target of gold. The pulse width was 800 ps and the laser energy is about 12 J. The emitted X-ray is analyzed by a pentaerythritol (PET) crystal spectrograph and recorded on Tianjing New-III X-ray films. On the assumption of the mono-temperature local-thermodynamic-equilibrium approximation, the electronic temperature is obtained from the intensity ratio of two unresolved transition arrays, and the experimental spectra is simulated.
