Abstract

The quasielastic scattering excitation functions for ¹⁶O + ¹⁵²Sm,¹⁷⁰Er and ¹⁷⁴Yb were measured with high precision at a backward angle with small energy intervals at energies near the Coulomb barriers. The hexadecapole deformation (β₄) of the target nuclei was extracted by using the lower-energy data and the obtained values agree with the available results reasonably well. This offers a sensitive method to extract β₄. This method is especially meaningful for the radioactive nuclei considering the low beam intensities.
