A new measurement of fusion cross-section for the system 4He+64Zn was performed at sub-barrier energy in order to cover the same energy region of previous measurements of 6He+64Zn. The fusion cross-section was obtained using an activation technique. From the comparison of the two excitation functions an enhancement of the fusion cross section was observed, at energy below the Coulomb barrier, in the reaction induced by 6He in respect to the one induced by 4He.
