INELASTIC CONTRIBUTIONS AND D-FUNCTION POLES

It is shown that the nonequivalence between the multichannel ND-1 method and the one-channel ND method incorporating inelasticity can be advantageously exploited in a fully dynamical scheme. It is demonstrated that the D-function poles needed for equivalence can be generated out of the inelastic cuts and that the pole parameters may be calculated from models of multichannel scattering. The result is an effective one-channel ND method, applicable to a class of problems wherein the incorporated inelastic effects are dynamically calculable. © 1968 The American Physical Society.
