Description

The Multi-Channel Algebraic-Scattering (MCAS) method, developed in 2003 for the analysis of low-energy nuclear spectra and of resonant scattering, continues to be effectively used for nuclear-structure studies. The MCAS approach allows the construction of the nucleon-core model Hamiltonian which can be defined in detail (coupling to the collective modes, rotational or vibrational, diverse components of the interaction operators, nonlocal effects due to Pauli exclusion). As reported at previous CAP congresses, MCAS analyses have given good descriptions of bound states and low-lying resonant spectra of medium-light nuclei, including nuclei well off the line of stability. This presentation deals with new directions for MCAS, specifically, moving to heavier target nuclei (mass A = 18-23) and new projectiles in the scattering process, recently, the α particle. New results will be shown for n+18O and p+18O, n+22Ne, and α scattering on targets from mass A=3 to A=16, the last of these yielding structure information for 20Ne.
