Title: Predicting Narrow States in the Spectrum of a Nucleus beyond the Proton Drip Line

Abstract

Properties of particle-unstable nuclei lying beyond the proton drip line can be ascertained by considering the (usually known) properties of its mirror neutron-rich system. We have used a multichannel algebraic scattering theory to map the known properties of the neutron-{sup 14}C system to those of the proton-{sup 14}O one from which we deduce that the particle-unstable {sup 15}F will have a spectrum of two low-lying broad resonances of positive parity and, at higher excitation, three narrow negative-parity ones. A key feature is to use coupling to Pauli-hindered states in the target.
