Abstract
The He+ + Ne collision system, in which the projectile electron as well as the target electrons undergo inelastic transitions is investigated in the i ndependent-particle model with a time-dependent screening potential. We use the basis generator method to solve the single-particle equations for all electrons and combine the transition probabilities statistically to calcula te charge-state correlated and more inclusive total cross sections in the e nergy range of 10 to 1000 keV/amu. Good agreement with available experiment al data is found except for the lowest projectile energies, where it is ind icated that a more refined dynamical screening model is required. We demons trate the importance of Pauli blocking for the electron transfer to the dre ssed projectile and discuss the role of the electron-electron interaction b etween projectile and target electrons, which is not included in our model.
