Description

A Multi-Channel Algebraic-Scattering (MCAS) method that was developed in 2003 for the analysis of low-energy nuclear spectra and of resonant scattering has continued to be effectively used for nuclear-structure studies. The focus now is on nuclei away from the valley of stability. Such nuclei are the subject of experimental study at Radioactive Ion Beam (RIB) facilities, and may have application to astrophysics. The MCAS approach allows the construction of the nucleon-core model Hamiltonian which can be defined in detail (coupling to the collective modes, 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. This presentation deals with new results for oxygen isotopes, and their mirror systems, using a vibrational model to construct the nucleon-nucleus potential matrices used in MCAS. New results will be shown for n+16O and p+16O, as well as preliminary results for nucleon plus 18O.
