The representations of fusion barrier distribution were derived from the quasielastic excitation function measured at the backward angle in 11B, 12C, 13C+209Bi reactions at energies around the Coulomb barrier. The experimental fusion barrier distributions were compared with the predictions of simplified coupled-channels fusion (CCDEF) calculations with inclusion of various channels coupling because of low-lying inelastic states of target and one and few nucleon transfers. The influence of neutron transfer coupling on fusion barrier distribution has been discussed.
