Abstract

New data for near-barrier ⁶Li, ⁷Be and ⁸B + ⁵⁸Ni elastic scattering enable a comparison of breakup coupling effects for these loosely-bound projectiles. Coupled Discretised Continuum Channels (CDCC) calculations suggest that the large total reaction cross sections for ⁸B + ⁵⁸Ni are dominated by breakup at near-barrier energies, unlike ⁶Li and ⁷Be where breakup makes a small contribution. In spite of this, the CDCC calculations show a small coupling influence due to breakup for ⁸B, in contrast to the situation for ⁶Li and ⁷Be. An examination of the S matrices gives a clue to this counter-intuitive behaviour.
