Abstract

High resolution measurements are made for Kα and Kβ X-rays from 33 MeV Ar ions passing through various foil targets. The average L-vacancy fraction at the Kα X-ray emission, the intensity ratio of the Kα hypersatellites relative to the Kα satellites and that of Kβ satellites relative to the Kα ones are obtained as a function of the atomic number of the targets, Z2. All of them show an oscillatory dependence on Z2 and discussions are made about this dependence by comparison with the previous work, particularly with the results of Watson et al. for 64 MeV S ions.

    Very fast some equilibrium charge is formed which affects the X-ray production. Therefore the reported X-ray production cross sections can be so called “equilibrium cross sections” as discussed in many earlier papers published [40–52]. This equilibrium charge formed inside the target is responsible to alter the X-ray production through electron capture processes.

    Citation Excerpt :

    In the case of the heavy-ion-induced X-ray spectra of target atoms, the multiple ionization of the M and L shells is extremely likely to occur [2–5]. Also in the case of the X-ray emission from the projectiles passing through different foils the multiple ionization of various shells of projectiles have been reported [6–11]. In recent years, several theoretical models for reliable description of very complex X-ray spectra accompanying the ionization (of both targets and projectiles) in collision processes based on the multiconfiguration Dirac–Fock (MCDF) method have been developed [5,12].
