“…At the resonance energies, the DCSs contain unique information on the partial wave dynamics of the collision process, i.e., the relation between ℓ in , ℓ res , and ℓ out . If the scattering were purely determined by a resonance without any background, the scattering matrix S would be given by the Breit-Wigner formula, originally developed for neutron scattering in 1936 and nowadays frequently used to describe scattering processes in high energy particle physics (24,25). However, in most cases and also in our experiments, the observed ICSs and DCSs result from an interference between resonance and background contributions.…”
