The total cross section for electron capture has been measured for H/sup +/, He/sup +/, N/sup +/, Ne/sup +/, Ar/sup +/, Kr/sup +/, and Xe/sup +/ incident on a Cs vapor target. The energy range investigated was 40--120 keV for incident protons, 30--140 keV for incident N/sup +/, and 20--200 keV for the incident noble-gas ions. Also measured was the total attenuation cross section for H/sub 2/ /sup +/, H/sub 3/ /sup +/, and N/sub 2/ /sup +/ incident on Cs in the energy range 30--160 keV. These attenuation cross sections result from either electron capture or breakup of the incident molecular ion. At velocities below 5 x 10/sup 5/ m/sec, the various cross sections are different both in magnitude and velocity dependence. In the velocity range (0.5--1.5) x 10/sup 6/ m/sec, the cross sections for the various incident ions are almost completely independent of the identity of the incident ion. At velocities above 1.5 x 10/sup 6/ m/sec, the individual cross sections are different from one another again. The behavior of the measured cross sections is discussed in terms of a theoretical model for near-resonant charge transfer. (AIP)
