Coulomb dissociation of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ in the field of ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ at different energies via resonance and continuum levels is discussed in detail. Relations are given which can be used to directly relate the Coulomb breakup cross section to the astrophysical S factor. Predictions for energy dependence and angular distributions are given. The direct Coulomb breakup of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ is found to be of the same order of magnitude as the sequential breakup at higher projectile energies. The effect to elastic scattering can be accounted for by introducing a dynamic polarization potential.
