Abstract A semiclassical approach has been used to study the effect of channel coupling on the calculations of the total fusion reaction cross section rfus, and the fusion barrier distribution Dfus for the systems 6He ?238U and 8He ?197Au. Since these systems invloves light exotic nuclei, breakup states channel play an important role that should be considered in the calculations. In semiclassical treatment, the relative motion between the projectile and target nuclei is approximated by a classical trajectory while
the intrinsic dynamics is handled by time-dependent quantum mechanics. The calculations of the total fusion cross section rfus, and the fusion barrier distribution Dfus are compared with the full quantum mechanical calculations using the coupled-channels calculations with all order coupling using the computer code and with the available experimental data.

Introduction
The effects of channel coupling in fusion reactions induced by light weakly bound projectiles have attracted great interest over the last decade [1–3]. Some theoreticalstudies predict strong influence of the breakup channel over the complete fusion (CF) cross section [4–10]. This has primarily been motivated by the present availability of radioactive ion beams, some of which exhibit unusual
features like halo/skin structure and large breakup probabilities. A critical understanding of the fusion mechanism
with radioactive ion beams is very significant for the understanding of reactions of astrophysical interest and for
the production of new nuclei near the drip lines [11–19]. The natural theoretical tool for their description is the
coupled-channel method. However, when a weakly bound collision partner is involved, breakup states channel play an
important role. Since they are in the continuum, an infinite number of channels should be taken into account. To
handle this situation, the continuum can be discretized by the continuum discretized coupled-channel method
(CDCC). However, the method is very complicated and requires considerable computer power. For practical purposes,
it becomes necessary to approximate the continuum by a finite set of states, as in the CDCC method [20–23].
This procedure has been extended to the case of fusion reactions in Refs. [8–10]. A semiclassical treatment
alternative based on the classical trajectory approximation of Alder and Winther (AW) [24] has been proposed by
Marta et al. [25].
