A Multi-Channel Algebraic Scattering (MCAS) theory has been used to study the interaction of a nucleon with light-mass nuclei as a coupled-channel problem. The method can be solved for all energies so that bound states as well as resonances of the compound nucleus can be specified, even if the compound nucleus is nucleon unstable. A resonance finding prescription ensures that all resonances of the system can be found no matter how weak and/or narrow. Spectra of mass-7 nuclei and of the proton unstable 15F are discussed, the Coulomb displacement energy considered, and first results on using MCAS details in a radiative capture cross section calculation presented.
