摘要：

Absolute state-selective electron-capture cross sections for charge transfer into the 3l state of C3+ in collisions of C4+ on H and H2 have been measured in the impact energy range of 0.05"1.33 keV/amu. The low-energy beams have been produced by retarding a 1.33-keV/amu C4+ beam (16 keV) by means of a five-element electrostatic lens system. The experimental results are compared with calculations based on molecular and atomic basis-set expansions. It turns out that especially for energies below 200 eV/amu there are considerable differences between experiment and theory both in relative and absolute 3l state-selective cross sections. © 1990 The American Physical Society.
