Comparative studies of the nonlinear effects occurring when highly charged projectiles collide with hydrogen, a free electron gas, and a harmonic oscillator
We calculate the nonlinear effects that appear at the level of the stopping cross section when heavy bare projectiles collide with both atomic hydrogen and a free electron gas. Calculations are carried out by using distorted-wave methods. For hydrogen targets we employ the continuum-distorted-wave e...
