    "abstract": "Recently measured high precision data of fusion excitation function have\nenabled a detailed study on the effects of nuclear collective excitations on\nfusion reactions. Using such highly accurate data of the $^{16}$O +\n$^{144,148}$Sm reactions, we discuss the anharmonic properties of collective\nphonon excitations in $^{144,148}$Sm nuclei. It is shown that subbarrier fusion\nreactions are strongly affected by the anharmonic effects and thus offer an\nalternative method to extract the static quadrupole moments of phonon states in\na spherical nucleus.",
