    Abstract

    To study the isoscalar giant resonances in a deformed case, background-free α-particle inelastic scattering measurements using a 386 MeV α beam were performed on the highly deformed Yb172 nucleus using the Grand Raiden spectrometer at the Research Center for Nuclear Physics (RCNP) at very forward angles, including 0∘. The strength distributions for the isoscalar giant resonances up to L≤3 were obtained using multipole decomposition analysis. The isoscalar giant monopole resonance (ISGMR) strength exhibits a splitting into two components, interpreted as the coupling of the ISGMR with the K=0 component of the isoscalar giant quadrupole resonance (ISGQR). A bimodal structure is observed in the strength distribution of the isoscalar giant dipole resonance. The ISGQR strength shows an enhancement near 25 MeV, attributed to the excitation of an overtone mode, while the broadening of the main-tone peak is associated with nuclear deformation. The experimental results are compared with theoretical strength distributions calculated using the quasiparticle finite amplitude method for L≤3.
