The (a + d) breakup of 60 MeV Li-6 scattered from Pb-208 has been measured inside the grazing angle for c.m. energies of the fragments between 100 keV and 1.5 MeV. The integrated cross sections are found to be in agreement with Coulomb excitation theory, but the angular correlations of nonresonant breakup exhibit significant deviations from this theory. This shows that the measured breakup cross section cannot be related by first-order Coulomb excitation theory to the astrophysically relevant He-4(d,gamma)Li-6 capture reaction.
