We have measured elastic excitation functions for the 7Li+27Al system, in an energy range close to its Coulomb barrier (Elab  =  8.4 MeV) in steps of 0.25 MeV. For this purpose, an array of eight surface‐barrier detectors was used. To get an insight on the background composition (mainly α particles), a telescope‐detector was used for atomic‐number identification. Identical measurements for the 6Li+27Al system are planned for the near future.
