dc.description.abstractA review is given on the use of the coupled-channel method to calculate the electronic and niuclear energy loss of ions penetrating the matter. This first principie calculation based on an expansion of the time dependent electronic wavefunction in terms of atomic orbitals lias been applied to evaluate the impact parameter dependence of the electronic energy loss, the stopping cross-section and the fluctuation in energy loss of ions colliding with H and He atoms at energies of 10keV/amu to 500keV/amu. The results have been compared to experimenta1 data as well as to others existing models e.g., local density approximation in an electron gas target, harmonic oscillator target treatment and first order plane-wave-Born approximationen
