Orbiting charge-transfer cross sections betweenHe+ions and cesium atoms at near-thermal ion-atom energies Academic Article uri icon


  • The energy dependence of the total charge-transfer cross section for the collision of helium ions with cesium atoms at epithermal energies (0.1 to 1 eV) has been measured. It was observed that the cross section increases with E-12. This can be attributed to orbiting collisions. The charge-transfer cross section is expressed as the product of the classical orbiting cross section and a quantum-mechanical charge-transfer probability which is shown to be energy independent. 1983 The American Physical Society.
