Methods will be discussed which allow one to eliminate, or determine more accurately, theoretical uncertainties associated with applying a 2-nucleon model to the (N,N{prime}{pi}) reaction at low momentum transfer to the nucleus (1 fm{sup {minus}1}). The reaction mechanism which describes the process at intermediate energies is delta dominant and is comprised mainly of 4 amplitudes. The nuclear spin-isospin selection rules make is possible for one amplitude to dominate the transition to a particular state. Three approaches are suggested for eliminating the theoretical uncertainties: (1) Using ratios of transition cross sections to different states. (2) Using ratios of different isobaric reaction cross sections for the same final state. (3) Rosenbluth plot techniques which allow one to distinguish between energy, scattering angle, and momentum dependent contributions to the reaction cross section.
