The spectra from laser-produced plasma have been simulated by the newly developed model. The simulation agrees well with the experimental results, which can prove that the K-shell model is suitable for the application of the spectrum from laser-produced plasma. Also, the jkl satellite lines were found important for predicting the spectra. [ABSTRACT FROM AUTHOR]

Extreme ultraviolet spectra of highly charged gold were produced with an electron beam ion trap at the University of Electro-Communications, Tokyo. The X-ray spectra (3240–3360 eV) of Au with well-defined maximum charge states ranging from Cu- to Se-like ions were recorded. Guided by configuration interaction calculations, the strongest 3d–5ftransitions have been well defined. [ABSTRACT FROM PUBLISHER]

The intercombination line (1s2p(3P1)−1s2) and the resonance line (1s2p(1P1)−1s2) of He-like Mo, which are the two electronic dipole transitions in theKα group emissions, are studied under dense plasma conditions by using the ion–sphere model combined with the multi-configuration Dirac–Fock model. The results show that the two electronic dipole transitions red shift nearly linearly with the increase in plasma electron density. Moreover, the red-shift energy becomes more sensitive to the plasma electron density, when the plasma electron temperature is lower. It is worth to note that the energy discrepancy between these two spectral lines is equal to the exchange energy of state 1s2p (3P1). This result may be useful to dense plasma diagnosis in connection with variation of the relative position and the spectral fine structure splitting in high-density plasmas. [ABSTRACT FROM PUBLISHER]
