Possible effects of hexadecapole nuclear deformations on subbarrier fusion cross sections are investigated. The O16 on Er166 and Yb176 reactions have been measured at beam energies ranging from 64 to 100 MeV. The Er166 and Yb176 data and already existing Sm154 data were analyzed in terms of a model including both quadrupole and hexadecapole deformations. Theoretical predictions follow qualitatively the trend of the experimental data. © 1991 The American Physical Society.
