Abstract

Measurements of the angular distributions of the single charge exchange reactions to isobaric analog states for C13(π+,π0)N13 and N15(π+,π0)O15 at 165 MeV are described. The two angular distributions are very similar. The shapes are reproduced by semiphenomeno-logical isobar-doorway calculations and by second-order coupled channels calculations. The calculated magnitudes are low by about a factor of 2. The measurements are consistent with older angle-integrated cross sections for C13. NUCLEAR REACTIONS C13, N15(π+,π0), Tπ=164 MeV; measured σ(θ); IAS transitions; enriched targets; test of reaction models.
