摘要：

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 near-barrier fusion of S-32 + Zr-90,Zr-94,Zr-96, O-16 + Ge-76, O-18 + Ge-74, and O-16,O-18 + Ni-58 are reported. Also a method, based on the CCFULL calculations with suitable inelastic couplings, to sort out the PQNT effect is presented.
