Abstract
We present a simple means of separating a partial-wave amplitude into a resonant term plus an inelastic background. The separation is exact if only one inelastic channel is present, but it should be a good approximation in the presence of more than one inelastic channel. Inequalities are obtained relating the elastic and inelastic widths to the background inelasticity. Comments are made regarding the application of the formalism.Keywords
