用放射化学方法研究了６．３—２４．６ＭｅＶ／ｕ４０Ａｒ＋ｎａｔＷ反应中Ｈｆ的生成，得到了Ｈｆ同位素的激发函数、反冲性质和同位素分布．指出利用ＨＩＲＦＬ能量的重离子和丰中子靶核作用，能以一定的截面生成Ａ＞１７０区丰中子新核素．利用中能重离子的强穿透力特点，使用厚靶，可以明显地提高丰中子新核素的产额．过高的入射能量对新核素生成无明显贡献．
The formation of Hf in 6.3-24.6MeV / u40Ar + natW reaction was studied by using the radiochemical method, and the excitation function, the recoil property and the isotopic distribution of Hf isotopes were obtained. It is pointed out that the heavy isotope neutron isotope A> 170 can be generated at a certain cross section by using the HIRFL energy heavy ion and neutron target. Utilizing the strong penetrating power of heavy ions in heavy metals, the use of thick target can obviously increase the yield of new neutron abundant neutron. High incident energy has no significant contribution to the formation of new nuclides.
