Results on the impact parameter dependence of L-shell vacancy production during heavy ion collisions are discussed in the frame-work of molecular orbital (MO) excitation mechanisms. It appears that excitation in the 4fsigma MO and vacancy transfer in the 3psigma, 3d..pi.., and 3dsigma MO through 3p..pi.. - 3psigma and 3ddelta - 3d..pi.. - 3dsigma rotational couplings reproduce fairly well experimental results for near-symmetric systems. Using the experimental results on the impact parameter dependence of the projectile L-vacancy production probability, the multiple collision process of Meyerhof et al. of 2psigma-vacancy production is considered in the case of I - Ag collisions. It is found that this process dominates K-vacancy production at large impact parameters, whereas at small impact parameter the experimental results can be explained by a single-collision direct excitation process from the coupled 2p..pi.. and 2psigma MO's. 24 references, 6 figures.
