The complete and incomplete fusion cross sections for the reaction were measured at near barrier energies by the online characteristic -ray detection technique. The complete fusion (CF) cross sections at energies above the Coulomb barrier were found to be suppressed by compared to the coupled channel calculations. Reduced fusion cross sections for the present system at energies normalized to the Coulomb barrier were also found to be systematically lower than those with strongly bound projectiles forming a similar compound nucleus. The suppression observed in CF cross sections is found to be commensurate with the measured total incomplete fusion (ICF) cross sections. In the ICF cross sections, -capture is found to be dominant than -capture at all the measured energies. The systematic study of available CF, ICF, and total fusion data with the projectile is performed.
