Abstract

The isoscalar giant dipole resonance (ISGDR) in Pb-208 has been investigated using inelastic scattering of 200 MeV alpha particles at and near 0 degrees where the angular distribution of the ISGDR can be clearly differentiated from those of other modes. The ''difference of spectra'' technique was employed to separate the ISGDR from the high-energy octupole resonance (HEOR). These data provide the dearest evidence yet for the ISGDR adjacent to the HEOR. With these results, all expected isoscalar lambda less than or equal to 3 resonances in Pb-208 have been identified.
