The spectra of multicharged ions produced by laser irradiation of moderate-Z (Z ≈ 40) and high-Z (Z ≈ 75) elements are dominated by tne dipole resonance lines of the isoelectronic sequences of neon and nickel, respectively. These spectra have been obtained for a large number of elements at the GRECO-ILM laser facility using both 0.26 μm and 0.53 μm laser wavelengths and 1013-1015 W/cm2 laser intensities. In addition to numerous electric dipole transitions, electric quadrupole resonance transitions have been measured and identified. The relativistic parametric potential method and the unresolved transition array (UTA) formalism support the identifications. Applications to laser-plasma diagnostics and laser-plasma X-ray sources will be emphasized.
