Coulomb Breakup ofLi6onPb208

The breakup of ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ in the Coulomb field of ${}_{}{}^{208}{}_{}{}^{}\mathrm{Pb}$ was studied at 20-, 21-, 24-, and 26-MeV incident energy. The discrepancies between the experimental and theoretical values indicate that some of the simplifying assumptions of the theoretical description have to be improved.
