This is thought to be related to their low thresholds for breakup into charged clusters. The observation of fusion suppression in the neutron-rich radioactive nucleus Li8 is therefore puzzling: the lowest breakup threshold yields Li7+n which cannot contribute to fusion suppression because Li7 retains all the projectile charge. In this work, the full characteristics of Li8 breakup in reactions with Bi209 are presented, including, for the first time, coincidence measurements of breakup into charged clusters. Correlations of cluster fragments show that most breakup occurs too slowly to significantly suppress fusion. However, a large cross section for unaccompanied α particles was found, suggesting that charge clustering, facilitating partial charge capture, rather than weak binding is the crucial factor in fusion suppression, which may therefore persist in exotic nuclides.application/pdfen-AU© 2018 American Physical Society201810.1103/PhysRevC.97.0216012019-11-25
