Isospin effect inπ*C14elastic scattering at 50 MeV

Angular distributions have been measured for ${\pi }^{\pm }$ elastic scattering at 50 MeV from ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}$. Comparison with previously measured distributions for ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$ shows a significant isotopic difference for ${\pi }^{\mathrm{-}}$ scattering. The data were analyzed using the second order Michigan State University optical potential proposed for low energy pion nucleus elastic scattering. Agreement with the data was obtained using the same density distributions for the protons and neutrons.
