Above-barrier complete fusion cross sections of weakly-bound 6,7Li and 9Be are known to be suppressed with respect to single-barrier penetration model calculations. Breakup of the projectile — either via direct excitation of continuum states, or by transfer of nucleons — is thought to be the cause, preventing complete capture of the projectile charge. Using the example of 7Li→8Be→ α + α we show how the contributions to breakup from different resonances in 8Be can be identified, and discuss their likely influence on fusion.
