Abstract
Radiation from argon with wavelength 8-85 nm has been measured with a grazing incidence spectrometer after excitation by 0.7 MeV/amu Cl11+ and 0.35 Mev/amu Cl9+ and Br14+. 417 lines have been identified. With a pulsed beam the radiation has been sorted into prompt and delayed fractions. Decay time analysis for separate peaks is correlated to charge state of the recoil ion. This leads especially to good assignment of Ar VII and Ar VIII lines. Delayed spectra do not depend much on projectile charge and velocity.
