Abstract We study the isospin dependence of the isoscalar giant quadrupole response to pion excitation, with the aim of showing that the apparent anomaly in the π−/π+ analyses is due to the highly selective nature of surface pion absorption. In that context, we present results of continuum RPA calculations which are consistent with recent inelastic pion scattering data on58–64Ni. In general, the calculation predicts a drastic increase in the ratio of neutron to proton transition density in going from56Ni to66Ni, a trend well substantiated by recent LAMPF experiments.
