LINE EMISSION AND ANISOTROPY EFFECTS IN C6+ ELECTRON-CAPTURE FROM LI(2S), LI-ASTERISK(2P) AND H-ASTERISK(N=2)

Line emission cross sections for visible transitions after electron capture collisions of C6+ With Li(2s), Li-*(2p), and H-*(n = 2) are calculated for energies up to 50 keV/u; the values agree with available Li(2s) data. Anisotropy parameters are also given for aligned Li-*(2p). The results were obtained by using the three-body classical trajectory Monte Carlo method with the application of a model potential based on Hartree-Fock calculations for the Li target. The visible line emission cross sections for Li-*(2p) and H-*(n = 2) targets are similar, indicating the experiments on Li*(2p) will provide needed plasma information for the difficult to measure H-*(n = 2) case.
