Abstract: Radiative collision processes between Li + and He have been studied in the projectile energy range from 0.45 to 4.2 keV. The total cross sections for Li(2p 2 P) and He(2p 1 P) excitations show the oscillations in antiphase with each other. A polarisation measurement was done for the 2p to 2s transition of Li; the degree of the polarisation is found to be relatively small in the energy range studied. The partial excitation cross sections for the magnetic sub-levels 2p 0 and 2p +or-1 of Li(2p 2 P) are obtained. On the basis of the sudden approximation, the kinematic effect in the polarisation measurement is discussed in detail.
