The 0/sup 0/ differential cross sections of (..pi../sup +/,..pi../sup 0/) reactions on a series of nuclei to isobaric analog states were determined at 165, 230, and 295 MeV. For each energy, the A dependence is well described by a power law of the form sigma = g(E)(N-Z)A/sup( -alphaE/), where ..cap alpha..(E) is a decreasing function of energy. The 0/sup 0/ excitation functions peak around the (3,3) resonance energy for all nuclei except /sup 90/Zr. A possible explanation in terms of neutron and proton densities is discussed.
