Crandall, D H

Recent research on electron transfer between multicharged ions and neutral targets is reviewed. The needs of astrophysics and thermonuclear fusion coupled with the availability of beams of slow multicharged ions have stimulated interest in these collisions. Data available on systems such as Ar/sup i+/ + Ar and Fe/sup i+/ + H indicate that cross sections as large as 10/sup -14/ cm/sup 2/ occur for transfer of an electron at collision velocities near and below the velocities of electrons in the atoms. In some cases, quantitatively correct predications of the cross sections have been based on a quasi-molecular model of the colliding system. This paper presents some of the available data, data needs, and comparison of experiment and theory for electron transfer at low collision velocities. A similar review was recently given by Salzborn, but already significant new results have been obtained.
