Résumé : The charge exchange Si 4+ + He reaction at low energy and high energy was studied. A time-dependent wave-packet approach was used in low energy range using two different propagator techniques. In high energy range, a semiclassical approach which included Coriolis effects was used. Split-operator technique was used in diabatic representaion and Chebyshev method was used in adiabatic representation for time-dependent approach. Two results were found to be in agreement and thus approved the accuracy of present approach. The order of the magnitude of theoretical values was confirmed by the rate constant of electron transfer reaction calculations.
