Abstract
A multi-channel algebraic scattering (MCAS) method has been used to obtain spectra of a number of light-mass nuclei, which are treated as a two-cluster system, here specifically a nucleon plus nucleus. To date, collective models have been used to specify the interactions between the nucleon and low-lying states of the nucleus that form the compound. For the case of the carbon isotopes, these studies have been complemented by sufficiently complex and complete shell-model calculations. Comparisons with the multi-ħω shell-model results provide new insights into the validity of those from MCAS.

multi-channel algebraic scattering (MCAS) is a multichannel algebraic scattering method [1] which has been used to obtain spectra of a number of light-mass nuclei, treating them as two-cluster systems, a nucleon plus nucleus in the cases discussed
Collective models have been used to specify the interactions between the nucleon and low-lying states of the nucleus that form the compound
As well as fitting the two known resonances in 15 F, narrow resonances above those were predicted by the MCAS calculations
Summary
MCAS is a multichannel algebraic scattering method [1] which has been used to obtain spectra of a number of light-mass nuclei, treating them as two-cluster systems, a nucleon plus nucleus in the cases discussed . Results of MCAS calculations on the mirror system 15 C (as n + 14 C) and 15 F (as p + 14 O). For the case of the carbon isotopes, these studies have been complemented by sufficiently complex and complete shell-model (SM) calculations.
