Analysis and simulation of XUV/EUV spectra of laser-produced gold, iodine and tin plasmas

The photoabsorption spectra of gold and iodine ions have been recorded using the Dual Laser-produced Plasma (DLP) technique in the 65 to 125 eV region, and the EUV emission spectra of tin ions have also been observed. With the aid of multiconfiguration Hartree-Fock calculations, the measured spectra have been identified. The dominant features in the gold spectra are 4f - 5d, 6d and 5p - 5d transitions arrays, while the iodine spectra arise from 4d - nf excitation, which evolves from 4d - εf shape resonance. The EUV spectra of tin plasma have also been simulated by combining the calculations of atomic data using the cowan code and a steady-state collisional radiative (CR) model. (author)
