Description
Isobaric-analog-state transitions have been observed throughout the periodic table in the (π+,π0) reaction. The forward-angle differential cross sections at T/sub π/=98 MeV on targets of CH2, 7Li, 13C, 27Al, 58Ni, 90Zr, 120Sn, and 208Pb are reported. The A dependence follows (N-Z)A/sup -4/3/, which is qualitatively understood in terms of a strong-absorption model. Optical-potential calculations which demonstrate the sensitivity to neutron density distributions and to the isospin dependence of higher-order dynamical effects are discussed
