Regular and chaotic regimes in coupled-channel calculations of nuclear scattering processes

The presence of regular and chaotic regimes in nuclear scattering processes has so far been established in the context of simple, schematic reaction models. It has been argued that traces of the underlying classical organization of phase space should also be present in complex quantal calculations performed with state-of-the-art coupled-channel codes. In this paper we show that this is indeed the case and develop concrete guidelines to infer - relying exclusively on features of the quantal results - the regular or chaotic character of the motion.
