This contribution reports the recent experimental studies for the coupling effect of the positive Q-value neutron transfer (PQNT) channels on near-barrier fusion with heavy-ions, measured by an electrostatic deflector setup. This effect is expected to be important in some situations. In this presentation, the experimental studies for the nearbarrier fusion of 32S + 90,94,96Zr, 16O + 76Ge, 18O + 74Ge, and 16,18O + 58Ni are reported. Also a method, based on the CCFULL calculations with suitable inelastic couplings, to sort out the PQNT effect is presented. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]
