Abstract: The effects of coupled-channels in heavy-ion fusion reaction for the system ⁴⁰Ca + ¹⁹²Os, ⁴⁰Ca + ¹⁹⁴Pt, and ⁴⁸Ca + ¹⁹⁷Au are discussed. The fusion cross-section σ_fus, the fusion barrier distribution D_fus and fusion probability P_fus are also discussed. The fusion barrier distribution is calculated using numerical three point, five point and Wong methods. Full quantum coupled-channels calculations are performed using CCFULL code with all order coupling to compare and with available experimental data. The χ² values for the case of no-coupling and coupling effects included shows clearly that the present calculations are in agreement with the experimental.

Keywords: Wong formula; coupled-channel; CCFULL code; heavy-ion.
