| Abstract: | Target atom excitations in collisions of He+ and He2+ with Li have been studied by optical measurement in the energy range q×(20-150) keV. We have measured Lil 670.8 nm (2p→2s), Lil 610.4 nm (3d→2p), Lil 460.3 nm (4d→2p) and Lil 812.6 nm (3s→2p) emission lines by using an OMA system. The emission cross sections of the observed lines and corresponding Li(2p) excitation cross sections have been calculated. For He+ +Li collision system, Lil 670.8 nm emission cross sections linked well with the results of Aumayr et al. at the low energy points. Our Lil 670.8 nm emission cross sections of He2++Li collision system agrees well with both the theory of Ermolaev er al. and the experimental results of Kadota et al. within the experimental errors. |
