We present new measurements and a general discussion of the behavior of the fusion, break-up and reaction cross sections of different projectiles on the same target ⁶⁴Zn, at near and above barrier energies. The projectiles are the tightly bound ¹⁶O, the stable weakly bound ⁶Li, ⁷Li and ⁹Be and the radioactive very weakly bound ⁶He nuclei. We also compare the results with the ones for heavier targets.
