Abstract

We estimate the accuracy of the conventional ansatz of approximating the lowest order absorptiveP-wave pion-deuteron interactions by pole term amplitudes. By comparing the matrix elements of the approximate pole term and complete absorptive reaction amplitudes for elasticπd scattering we find the pole term approximation to lead to better than 10% accuracy for both theP 11 andP 33 state interactions.
