Charge exchange induced by collisions with electrons is considered. It is shown that in a plasma under certain conditions, three-body collisions resulting in charge exchange become significant at electron densities n/sub e/ of approx.10/sup 12/ cm/sup -3/. As an example, it is shown that for an Rb-Cs plasma with atomic velocities v/sub n/ of approx.10/sup 6/ cm/sec, electron velocities v/sub e/ of approx.7x10/sup 7/ cm/sec, and a resonance defect n/sub 0/ of approx.0.28 eV, the electron-induced charge exchange cross section is 3x10/sup -32/n/sub e/ cm/sup 2/; this is a thousand times greater than the charge exchange cross section calculated with allowance for Coulomb detuning (R. Z. Vitlina and A. V. Chaplik, Zh. Eksp. Teor. Fiz. 70, 543 (1976)/Sov. Phys.-JETP 43, 280 (1976)/). It is also shown that in a cesium plasma the decrease in the resonance charge exchange cross section due to Coulomb detuning is compensated by charge exchange induced by electron collisions.
