The ({alpha}+{ital d}) breakup of 60 MeV {sup 6}Li scattered from {sup 208}Pb has been measured inside the grazing angle for c.m. energies of the fragments between 100 keV and 1.5 MeV. We find the integrated cross sections 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 {sup 4}He({ital d},{gamma}){sup 6}Li capture reaction.
