UNITARITY AND REDUCTION FORMULAS; PRELIMINARY VERSION.
Abstract
The content of x-space reduction formulas in q-space is discussed using the example of fermion-boson scattering. The splitting of the T-operator is shown to correspond to a natural decomposition of the unitarity condition for T, and may be deduced from unitarity alone. Reality conditions for M sub 1 are derived from q-space properties without reference to x-space. Necessary and sufficient conditions are given for T being unitary. Iteration methods are developed which lead to a determination of elastic amplitudes starting with one-particleexchange-contributions, i.e., pole terms and form factors, and the whole contribution from inelastic processes as input force. The essential part of the iteration method is a prescription to construct off-shell elements, especially off-shell-one-particle-exchange-contributions.
