Abstract

Forward-angle differential cross sections for the isobaric-analog state in the C14(π+, π0)N14 reaction were measured at 100, 165, 230, and 295 MeV. The extracted excitation function is found to have a maximum near 200 MeV and its shape resembles that of the free πN cross sections. Impulse-approximation calculations with optical potentials linear in the nuclear density do not reproduce the trends of the data. Systematics of 0° cross sections with N and Z are presented.
