T. Kirchner et M. Horbatsch, Nonperturbative calculation of projectile-electron loss, target ionization, and capture in He++Ne collisions - art. no. 062718, PHYS REV A, 6306(6), 2001, pp. 2718
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.
