Mass-15 nuclei and predicting narrow states beyond the proton drip line

In a previous Letter [Phys. Rev. Lett. 96, 072502 (2006)PRLTAO0031-900710.1103/PhysRevLett.96.072502], the multichannel algebraic scattering (MCAS) technique was used to calculate spectral properties for proton-unstable F15 and its mirror, C15. This achieved a close match to the then-new data for p+O14 elastic scattering and predicted several unusually narrow resonances at higher energies. Subsequently, such narrow resonance states were discovered. New cross section data has been published characterizing the shape of the Jπ=12- resonance. Herein we update that first MCAS analysis and its predictions. We also study the spectra of the set of mass-15 isobars C15, N15, O15, and F15, using the MCAS method seeking a consistent Hamiltonian for clusterization with a neutron and a proton, separately, coupled to core nuclei C14 and O14.
