INTERPRETATION OF THE N* EFFECT IN DEUTERON COMPTON SCATTERING.
Abstract
Calculations of deuteron Compton scattering based on impulse methods demonstrate a peaking of the energy distributions due to the N* pole in the factored nucleon amplitude. It is suggested that the factorization procedure is questionable when a pole exists in the factored amplitude, as is evidenced, for example, by the failure of the impulse technique near threshold where the nucleon pole term is of importance. This difficulty is obviated by correctly treating the N* as an intermediate state. An expression for the deuteron Compton differential cross section was derived. To avoid ambiguities inherent in the spin case, scalar particles were used. A comparison with the limited experimental data available above the photopion threshold produced very encouraging results.
