Compression mode giant resonances have been measured in many nuclei from C to Pb with inelastic scattering of 240 MeV ∀ particles at small angles. Isoscalar monopole (GMR) distributions have been extracted for 17 nuclei and isoscalar dipole (ISDGR) distributions extracted for 11 nuclei. The isoscalar E1 strength distributions in nuclei with A>90 are found to consist of a broad component at Ex ≈ 75/A MeV containing 15-40% of the total isoscalar E1 strength. The GMR results lead to Knm=215-240… Expand
