“…In recent works [10,11,12,13], we have extended the method to include the possibility that the target excited states may themselves be unstable resonant states. This capability gives a more realistic description of the coupled-channel problem and leads, generally, to widths of resonant states in the compound system that include effectively other decay channels, beyond the single nucleon emission decay.…”

A multi-channel algebraic scattering (MCAS) method has been developed to obtain spectra of a number of light-mass nuclei, which are treated as two-cluster systems. The method has been applied to a variety of cases that could be described as nucleon-core systems, but also alpha-core systems have been treated. The MCAS method gives sub-threshold/bound-state spectra, describes resonances, from the very narrow to the broad ones, and provides various scattering/reaction observables. Collective models have been used to specify the interactions between the projectile and low-lying states of the target nucleus that form the compound. In this contribution we discuss in particular some resonance features in the scattering of the p + 14 O and p + 6 He systems.

A multi-channel algebraic scattering (MCAS) method has been used to solve coupled sets of Lippmann-Schwinger equations for the α+ 6 He cluster system, so finding a model spectrum for 10 Be to more than 10 MeV excitation. Three states of 6 He are included and the resonance character of the two excited states taken into account in finding solutions. A model Hamiltonian has been found that gives very good agreement with the known bound states and with some low-lying resonances of 10 Be. More resonance states are predicted than have as yet been observed. The method also yields S-matrices which we have used to evaluate low-energy 6 He-α scattering cross sections. Reasonable reproduction of low-energy differential cross sections and of energy variation of cross sections measured at fixed scattering angles is found.
