In this work we report calculations of the impact parameter dependent energy loss and charge exchange cross section of4He+ions on atomic neon by taking into account the dynamics of both electrons and nuclei. The results are obtained for projectiles energies ranging from a few eV/amu up to 100 keV/amu. We also report the nuclear and electronic contribution to the total stopping cross section. Comparison of the present results for this channel with the available experimental data shows good agreement. ©2001 American Institute of Physics.
