Charge-state distributions and the population of x-ray emitting states

Abstract

The population of excited states of neon projectiles has been deduced from highresolution x-ray spectra. From the comparison of the satellite and the hypersatellite spectrum we conclude that the population of the outer shells is insensitive to the presence of either one or two K-shell vacancies. On the basis of a model of independent electrons the population distribution including states with filled K-shell can be estimated. The deduced mean charge states compare rather well with results obtained from beam analysis over a projectile energy range from 5 to 18 MeV.

Collisional configuration-rearrangement in fast neon projectiles

“…The advance of the crystal angle in steps of 0.02 ~ was effected by stepping motors. The motor control in function of the integrated beam current in the Faraday cup, as well as the recording of the data was accomplished by a computer-independent CAMAC system [12]. The energy calibration of the spectrometer was obtained without target gas but with a carbon foil at the viewing region of the spectrometer by attributing the well known 1S-1P transition and the ls-2p transition [13], respectively, to the most energetic and quite intense lines of the K e-satellite and K ehypersatellite groups.…”
