Distorted-wave cross sections for electron-impact ionization of Ar{sup 7+}
- Atomic Processes Group, Lawrence Livermore National Laboratory, Livermore, California 94550 (United States)
Distorted-wave methods have been used to calculate cross sections for electron-impact ionization of sodiumlike Ar{sup 7+} for collision energies ranging from near threshold to 1 keV. We included contributions due to excitation-autoionization and resonant excitation{endash}double autoionization (REDA), as well as the contributions from direct ionization of the 3{ital s} electron and the {ital n}=2 inner-shell electrons. We find that the effects of radiative damping and loss channels reduce the REDA contributions by a factor of 4. We compare our calculated results to experimental results and to theoretical cross sections obtained in a close-coupling approximation. {copyright} {ital 1996 The American Physical Society.}
