Looking For The Isoscalar Giant-Dipole Resonance In Pb-208 Using Inelastic Alpha-Scattering At And Near 0-Degrees

The isoscalar giant dipole resonance (ISGDR) in Pb-208 has been investigated using inelastic, scattering of 200 MeV a particles at and near 0-degrees where the angular distribution of the ISGDR can be clearly differentiated from other modes. The ''difference of spectra'' technique was employed to separate the contribution from the high-energy octupole resonance (HEOR). Results from a preliminary analysis of the data are consistent with the expected positions of the ISGDR and HEOR, as well as their expected angular distributions near 0-degrees.
