(Received 12 May 2003; accepted in final form 21 August 2003)

The elastic-scattering, neutron transfer and projectile break-up channels have been studied for the reaction $\chem{{}^{6}He+{}^{64}Zn}$ at energies around the Coulomb barrier. The results show a very large break-up and transfer cross-section corresponding to the largest fraction of the total reaction cross-section. No evidence of threshold anomaly emerged from the elastic-scattering optical-model analysis.
