摘要：

Radiation from a neon gas has been measured after exposure to a pulsed, fast, highly charged ion beam for wavelengths 8 to 60 nm, with a 2. 2 m grazing-incidence spectrometer in scanning mode. The time relative to the exciting beam was recorded together with the wavelength in list mode. Results are shown for 0. 7 Mev/amu Cl**1**1** plus and 0. 35 Mev/amu Br**1**4** plus beams, sorted in prompt and delayed fractions and total for 0. 45 Mev Ne** plus . Excited states of the Ne**q** plus , q equals 1-6, are found to be both directly produced in a single collision and a consequence of capture of electrons into originally higher charge states, accounting for a high fraction of the emitted radiation even at low pressures in the recoil ion source.
