    Samenvatting

    Background-free inelastic scattering spectra have been obtained for the Sm isotopes with 400 MeV alpha particles at forward angles (including 0degrees) to investigate the effect of deformation on the compressional-mode giant resonances. The strength distributions for the isoscalar giant resonances (L <3) have been extracted for the spherical nucleus Sm-144 and the deformed nucleus (SM)-S-154. We have observed that the effects of deformation are different for the low- and high-excitation-energy components of the isoscalar giant dipole resonance in Sm-154. Evidence for the theoretically predicted coupling between the isoscalar dipole resonance and the high-energy octupole resonance is reported.
