摘要：
We investigate the apparent anomaly inherent to π-/π+ scattering results on giant quadrupole resonances compared to data emanating from other probes. Our study focuses on the radial dependence of the π+ and π- cross sections using the eikonal and the random phase approximations. Our conclusion is that, once the highly selective nature of the surface pion absorption process is taken into account, there is indeed consistency between pion, electron and proton scattering and microscopic theories regarding the isoscalar nature of the GQR. © 1990.
