| Abstract: | The X-ray spectra emitted from laser-produced Au plasmas in the range 0.3-0.4nm were analyzied and interpreted by using the Spin-Orbit-Splitted Array model. The plasmas were created by using a beam of a frequency-tripled 1.05m m Nd-glass laser focused onto a microdot target of gold.The pulse width was 800ps and the laser energy was about 12J. The emitted X-ray was analyzed by a pentaerythritol(PET) crystal spectrograph and recorded on Tianjing New-III X-ray films. On the assumption of the mono-temperatured local-thermodynamical-equilibrium approximation, the electronic temperature was obtained from the intensity ratio of two unresolved transition arrays, and the experimental spectra were simulated. |
