Electron-impact ionization of Zn+ and Ga+
- 1. Joint Institute for Laboratory Astrophysics, University of Colorado and National Bureau of Standards, Boulder, Colorado 80309
Description
Absolute cross sections for electron-impact ionization of Zn+ and Ga+ have been measured from below threshold to 2 keV with the use of the crossed-charged-beams technique. Excitation autoionization was shown to be of major importance in both ions for the region between 1 and 2 times threshold, leading to enhancement of the cross sections by factors of up to approx.2.5. Discrepancies between experiment and the well-known semiempirical formula of Lotz were up to 70%, but reduction of Lotz's a/sub 3d/ coefficient by a factor of 2 leads to satisfactory agreement at high energies. Comparison is also made with scaled-Born-approximation calculations
