Benchmarking models of breakup reactions

The continuum discretised couple-channel model (CDCC) and the dynamical eikonal approximation (DEA) are two state-of-the-art models used to study the breakup of halo nuclei. In this work, we compare them for the breakup of C-15 on Pb at 68AMeV. Excellent agreement is obtained for both energy and angular distributions. Slight discrepancy is observed in the contributions of some partial waves, which might affect other breakup observables, like momentum distributions. The use of relativistic velocity has little effect on the energy distribution, but affects more significantly the angular distribution.
