We suggest a situation in which one might observe a two-peak structure which is in fact a single, broad, inelastic resonance. Starting with an inelastic factor $\eta$ which has a single smooth dip, but differs somewhat from a Breit-Wigner form, we find that the Ball-Frazer mechanism generates a two-peak resonance.
