摘要：

CAM (complex angular momentum) results for Mie resonances and for the associated ripple fluctuations in Mie scattering are reported. Resonance positions and widths are accurately determined. They are described by Regge trajectories, that are found also to produce strong antiresonant contributions. The background includes a new forward glory term. CAM theory provides a physical picture of all contributions and the first accurate non-partial-wave fit of the total cross section including both background and ripple. The backscattering cross section is also reproduced: both background (dominated by tunneling) and resonance contributions must be taken into account.
