The interplay of nuclear and Coulomb contributions to breakup processes is studied theoretically. This is especially relevant for the extraction of astrophysical {ital S} factors for radiative-capture reactions. We study explicitly the breakup of {sup 6}Li and {sup 7}Li projectiles. Results of our calculations are in good agreement with recent experimental data. The different behavior of the nuclear and Coulomb amplitudes as a function of angle and energy helps to separate them from each other. This is vital for reliable extraction of astrophysical {ital S} factors of radiative-capture processes from breakup experiments.
