Comparing nonperturbative models of the breakup of neutron-halo nuclei

Breakup reactions of loosely bound nuclei are often used to extract structure and/or astrophysical information. Here we compare three nonperturbative reaction theories often used when analyzing breakup experiments, namely the continuum discretized coupled channel model, the time-dependent approach relying on a semiclassical approximation, and the dynamical eikonal approximation. Our test case consists of the breakup of ¹⁵C on Pb at 68 MeV/nucleon and 20 MeV/nucleon.
