Systematic study of channeling stopping-power oscillations for low-velocity heavy ions

The model used by Briggs and Pathak to calculate the electronic energy loss of low-velocity channeled heavy ions has been explored further to study the velocity dependence of Z1 oscillations in electronic stopping power. For increasing ion velocities, where the validity of neglecting the target-electron velocities increases, it is found that the magnitude of Z1 oscillations decreases and by about 2-a.u. velocity the first maxima at Z1=6 and the first minima at Z1=10 are washed out completely
