Abstract
In this work, two classical models which have been proposed to describe He atoms in collision processes by charged particle impact are revisited and analyzed. These are the Heisenberg-core and the energy-bounded classical trajectory Monte Carlo methods. These models avoid the classical autoionization by introducing in the Hamiltonian momentum-dependent terms. The physical implication of different choices of the involved parameters are analyzed as well as their influence at the total cross section level.
