MOBILITY OF POSITIVE IONS IN THEIR OWN GAS:nDETERMINATION OF AVERAGE MOMENTUM-TRANSFER CROSS SECTION

摘要

The average momentum cross section obtained from this equation can be used to compare energy-dependent charge exchange cross section data with mobility data;this is illustrated by an example for several inert gas ions in their own gas. The average momentum cross section has also been used to compute the mobility of alkali-metal ions in their own vapor. The calculations reveal errors in earlier numerical approaches.
