Abstract
Absolute emission cross sections have been measured for 29 lines of the C IV spectrum in the wavelength range 20-500 nm resulting from C4+-Li collisions at impact energies between 0.83 and 6.67 keV amu-1. From these emission cross sections one-electron capture cross sections sigma nl have been deduced for all subshells with n-14 cm2 which is almost independent of energy. The distributions over l subshells within each n shell are strongly energy dependent, shifting to larger values of l with increasing energy. However, capture into the 5g subshell is dominant over the whole energy range. The results are partly explained qualitatively and are in good agreement with very recent calculations by Fritsch and Lin (1983) who used a modified two-centre atomic orbital expansion.Keywords
