Abstract
We have measured the differential cross sections of the (,) reaction on , , and to the ground state of the final nucleus (, , ) at MeV and . We treat the nuclei as elementary particles, extract the initial-nucleus-pion-final-nucleus coupling constants, and compare them with predictions based on the partial conservation of axial-vector current hypothesis. The calculations, which have no free parameters, agree with the data for and , but not for .
