Abstract：
The yields of known hafnium isotopes produced in 6.3-24.6MeV/u ⁴⁰Ar+^natW reactions were determined by γ-ray spectroscopy following radiochemical separations.The excitation functions,FW values and isotope distributions of hafnium were obtained.It is indicated that synthesis of new heavy neutron-rich isotopes is possible through the reactions induced by heavy ions at HIRFL energy region.The thick target is favorable for increasing the yields of neutron-rich nuclides far from the β-stability. However, further increasing incident energy is not always helpful to synthesize neutron-rich isotopes.
