Abstract：
The yields of known hafnium isotopes produced in 6.3-24.6 MeV/nucleon ⁴⁰Ar+ ^natW reactions were determined by γ-ray spectroscopy following chemical separation. The excitation function, the FWvalue, and isotope distributions were obtained. It was deduced that using HIRFL energy heavy ions to synthesize new neutron-rich nuclides in the A> 170 region is possible. Using thick target or multi-thin target can obviously increase the yield of a new neutron-rich nuclide. Increasing projectile energy is not always helpful to synthesize a new neutron-rich nuclide.
