The isoscalar giant quadrupole resonance is studied in /sup 118/Sn(..pi../sup + -/,..pi../sup + -/') at 130 MeV. It is found that the ratio of ..pi../sup -/ to ..pi../sup +/ cross sections at their maximum is 1.9 and that 57% of the energy-weighted sum rule is exhausted in ..pi../sup -/ scattering. This large ratio of ..pi../sup -/ to ..pi../sup +/ cross sections is not anticipated by conventional models, and may be interpreted as evidence for substantial isovector strength.
