Longitudinal momentum distributions in ionization of helium by fast, highly charged projectiles

The longitudinal momentum distributions for the recoil ion, the electron and the projectile momentum transfer in single ionization of He by 3.6 MeV amu-1 Ni24+ impact are calculated using the cdw-eis method within the independent electron approximation. Results are compared with the measurements and...

Sumario:The longitudinal momentum distributions for the recoil ion, the electron and the projectile momentum transfer in single ionization of He by 3.6 MeV amu-1 Ni24+ impact are calculated using the cdw-eis method within the independent electron approximation. Results are compared with the measurements and CTMC calculations of Moshammer et al (1994). it is found that the cdw-ejs theory explains qualitatively the observed enhancement of the electron distribution in the forward direction, and the enhancement of the recoil-ion distribution in the backward direction. Our calculations show discrepancies with the measurement regarding the positions for the maxima of these distributions. A calculated electron energy spectrum is in good agreement with the measurement. © 1995 IOP Publishing Ltd.
