Abstract:
The validity of describing the α-nucleus scattering in terms of trajectories of complex angular momentum poles for the scattering matrix is investigated through analyses of the differential cross sections in 12C(α,α)12C and 16O(α,α)16O. The trajectories and the complex angular momentum representations of the partial wave amplitude are set up for the rotational bands with definite parities. The adequacy of regarding a trajectory as the reflection of a rotational intrinsic-state is deduced and a resonance width is ascribed to the mixings of nonresonant angular momenta.
