Abstract
The authors illustrate the relationship between square-root branch points of energy eigenvalues and the decay rates of metastable states in a simple model in quantum mechanics involving decay through a delta-function potential barrier. The 'infinite volume' limit of the cut-structure is found to have an interesting pathology.
