Abstract
We report for the first time specific (1s nl) 1L and 3L projectile excitation cross sections of 280 keV ( v=1.26 a.u.) Li ++He collisions. Strong production of triplet states is observed in the (1s nl) distribution of the Li II Rydberg states. We suggest that final state singlet-triplet mixing of the Rydberg manifold in conjunction with cascade repopulation may considerably modify the population of high spin states.
