Abstract

The systematic behavior of the isoscalar giant dipole resonance (ISGDR) in 90Zr, 116Sn, 144Sm, and 208Pb is studied with inelastic α scattering at Eα=386 MeV. Multipole-decomposition analysis is applied to extract the excitation strengths of giant resonances from the (α, α′) differential cross sections at θlab=0.64°-13.5°. The bimodal structure of the ISGDR is discussed and compared with recent theoretical results from Hartree-Fock+random-phase-approximation calculations.
