Abstract
The Chew-Low extrapolation as applied to the nucleon-deuteron breakup reaction is studied. Singularities of the amplitude and cross sections are located using perturbation theory and simple final-state interaction theory. The measured cross sections, whose kinematic singularities are exhibited, are expressed in terms of the invariant Chew-Low cross sections. The experimental procedure is outlined, and forms are suggested for the fitting curves.
