Abstract

The authors investigate the apparent anomaly inherent to pi ^-/ pi ⁺ scattering results on giant quadrupole resonances compared to data emanating from other probes. Their study focuses on the radial dependence of the pi ⁺ and pi ^- cross sections based on a continuum RPA calculation for ²⁰⁸Pb. Their conclusion is that, once the highly selective nature of the surface pion absorption process is taken into account, there is indeed consistency between pion and hadron scattering and microscopic theories regarding the isoscalar nature of the GQR.
