We introduce two active-electron classical trajectory Monte Carlo models for ion-He collisions, in which the electron-electron force is smoothed using a Gaussian kernel approximation for the pointwise classical particles. A first model uses independent pairs of Gaussian electrons, while a second one employs time-dependent mean-field theory to define an averaged electron-electron repulsion force. These models are implemented for prototypical p+He collisions and the results are compared to available experimental and theoretical data.
