Values of the cross sections for direct break-up of 7Li projectiles at forward scattering angles have been determined for 50, 60 and 70 MeV projectile energies and for 96Zr, 120Sn and 208Pb targets. The results for 96Zr and 120Sn targets are in reasonable agreement with the predictions of a model that assumes the target-projectile Coulomb interaction is responsible for direct break-up. Results for 208Pb show significant deviations from this model.

Measurements are reported for the elastic and inelastic (478 keV excited state) scattering of 68 MeV7Li from a208Pb target. These are compared with coupled-channels and high-energy adiabatic model calculations, using an alpha-triton cluster structure description of7Li. In contrast to the results of fitting to the breakup cross sections, the purely nuclear contributions to the inelastic processes are too small in both models. Inclusion of a Coulomb amplitude in the coupled-channel calculation helps to fit the cross section at angles down to the grazing angle, but is too large at smaller angles. A DWBA Coulomb correction to the adiabatic model improves its ability to fit the data at angles except near grazing.

The direct breakup of 70-MeV $^{7}\mathrm{Li}$ scattered from a $^{120}\mathrm{Sn}$ target is investigated at forward angles. Inside the grazing angle, it is found that the breakup is dominated by the Coulomb interaction between projectile and target.
