Charge transfer and ionization by positive ions in the energy range 60 to 450 keV

Abstract

Charge transfer and ionization by singly charged positive ions have been investigated by means of a variation of the well-known condenser method in which slow charge collection over a precisely determined path length is carried out at pressures low enough to ensure single collision conditions; a uniform axial magnetic field enables total slow ion currents to be measured. The apparent total charge transfer cross-section, the total electron production cross-section and the total slow ion production cross-section have been determined for seventeen cases involving rare gas ions in the rare gases and hydrogen.
