Abstract
When the neutron- or proton-excess in a given nuclide becomes too large, the last nucleon becomes unbound and the nuclide decays by emitting a neutron or proton. The time scale for this nucleon emission can be extremely short. Sometimes these systems are only referred to as resonances rather than nuclides. The chapter describes the discovery of neutron- as well as proton-unbound nuclides and resonances.
