  One theoretical method for studying nuclear scattering and resonances is via
the multi-channel algebraic scattering (MCAS) formalism. Studies to date with
this method have used a simple collective-rotor prescription to model target
states with which a nucleon couples. While generally these target states all
belong to the same rotational band, for certain systems it is necessary to
include coupling to states outside of that main band. Here, we extend MCAS to
allow coupling of different strengths between such states and the rotor band.
This is an essential consideration in studying the example examined herein, the
scattering of neutrons from 22Ne.
