INTERFERENCE IN THE UNITARITY RELATION IN FEW-BODY DYNAMICS

The various terms present in the unitarity relation for elastic and in elastic nucleon-nucleon scattering are studied in a three-body model. Because of the three-body dynamics one can determine a special interfe rence term contributing to the total cross section. This interference term can be positive or negative. The explicit calculation of this ter m may serve as a check on three-body calculations. It also provides a measure of the actual importance of three-body dynamics in a particula r model.
