Mass-15 nuclei and predicting narrow states beyond the proton drip line
Abstract
In a previous letter (Phys. Rev. Lett. 96, 072502 (2006)), the multi-channel algebraic scattering (MCAS) technique was used to calculate spectral properties for proton-unstable F and its mirror, C. MCAS achieved a close match to the then-new data for O elastic scattering and predicted several unusually narrow resonances at higher energies. Subsequently, such narrow resonance states were found. New cross section data has been published characterising the shape of the resonance. Herein we update that first MCAS analysis and its predictions. We also study the spectra of the set of mass-15 isobars, C, N, O, and F, using the MCAS method and seeking a consistent Hamiltonian for clusterisation with a neutron and a proton, separately, coupled to core nuclei C and O.
