Abstract

The systematic behavior of the isoscalar giant dipole resonance (ISGDR) in ⁹⁰Zr, ¹¹⁶Sn, ¹⁴⁴Sm, and ²⁰⁸Pb is studied with inelastic α scattering at E_α=386 MeV. Multipole-decomposition analysis is applied to extract the excitation strengths of giant resonances from the (α, α′) differential cross sections at θ_lab=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.
