ELECTRON-ION AND ION-ION RECOMBINATION,
Abstract
Information obtained from laboratory experiments and theoretical calculations concerning electron ion and ion-ion recombination processes is re viewed. It is concluded that the two-boc esses of dissociative recombination and radia tive recombination between electrons and positive ions and of mutual neutralization of positive and negative ions are of importance for the iono sphere. Laboratory aferglow measurements on ions of ionospheric interest yield values for the dissociative recombination coefficients. Theoretical calculations yield radiative recom bination values for H(), He(), O() ions and electrons of 4-5 x 10 to the -12th power cc/sec at 250 K and a T(sub e) sup-0.5 dependence on electron temperature. Auxiliary processes affect ing ionospheric recombination, such as electron attachment to O2 molecules, charge transfer both for positive ions and negative ions, and ion conversion, are briefly considered.
