The impact of highly charged and high energy ions in a gas target produces excited recoil-ions. The speed of these ions being quite low, the Doppler shifts and broadening of emitted lines are very small. With a Kr 20+ beam at 1.15 MeV/amu, we have observed the spectra of Ne ions in the wavelength range 60-570 Å and of Ar ions in the range 150-290 Å. In the first one, 130 lines have been identified, classified and compared to previous results. In the second one, 55 lines have been observed, 12 transitions unknown up to now are determined and compared to similar transitions for isoelectronic ions. The 3 p 4 d configuration in Ar V is analysed, taking into account the intermediate coupling.
