Abstract : Use has been made of the interference between the nuclear and Coulomb amplitudes in the scattering of 84 MeV/nucleon 17O ions by 124Sn to study the isospin character of the giant quadrupole transition. The data are well described by assuming the transition is ''isoscalar,'' i.e., Mn/Mp=N/Z. This is in disagreement with the results of π+/π- scattering on 118Sn and recent (e,e'n) measurements on 116Sn. Cross sections for excitation of the 2+ state at 1.132 MeV, 3- state at 2.614 MeV, and giant monopole resonance are included with corresponding coupled-channels calculations.
