Isoscalar E0-E3 strength in 116Sn, 144Sm, 154Sm, and 208Pb -: art. no. 034315

The giant resonance region from 10 MeV<55 MeV in Sn-116, Sm-144, Sm-154, and Pb-208 has been studied with inelastic scattering of 240 MeV alpha particles at small angles including 0degrees. Essentially all of the expected isoscalar E0, E1, E2, and E3 strength was identified in these nuclei.
