Abstract:

The charge transfer cross section for cesium ions and atoms was measured as a function of interaction velocity in the range 2 x 10 to the 6th power cmsec to 1.2 x 10 to the 7th power cmsec 300 ev to 10 kev. The measurements were made using crossed ion and atom beams with the atom beam chopped. The data fits a curve the square root of sigma equals A-B log v10 to the 6th power cm with A equals 1.96 x 10 to the -7th power cm and B equals 0.85 x 10 to the -7th power cm. The general form of this curve is in agreement with theory although the constants do not agree closely with any theoretical calculation. In the Appendix, the data are applied to the calculation of a limit on ion motor operation lifetimes. Author
