In recent years, we have developed a Multi-Channel Algebraic Scattering (MCAS) approach to study low-energy nucleon-nucleus scattering, resonance phenomena, and sub-threshold spectra for medium-light nuclei. We have considered compound nuclei that are stable, or weakly bound, and have also extended the analysis to very unstable systems that are unbound with respect to proton emission, namely, that are beyond the proton drip line. More recent developments concerned the application of the MCAS approach to the analysis of the spectra of two hypernuclear systems, 9δBe and 13δC. We have studied the splitting of the two odd-parity excited levels (1/2- and 3/2-) at 11 MeV excitation in 13δC, finding that it is driven mainly by the weak λ-nucleus spin-orbit force. Conversely, the splittings of the 3/2+ and 5/2+ levels in both 9 λBe and 13λC originate from couplings to the collective 2+ states of the core nuclei. In both hypernuclei, our MCAS-based calculations suggest that there are additional low-lying resonant states in the δ-nucleus continua. From the MCAS approach one can extract also the full coupled-channel scattering wave function to be used in the calculation of various transition matrix elements. As a first application, we have considered the EM-transition matrix elements for the capture reaction of astrophysical interest: α + 3He → 7Be + γ.
