用（ｎ，２ｐ）反应和快化分离法首次合成和鉴别了新丰中子同位素￣（１８５）Ｈｆ。其半衰期为３．５±０．６ｍｉｎ。另外，还观察到一条能量为１６４．５±０．５ｋｅＶ、半衰期为４．３±０．９ｍｉｎ的属于￣（１８５）Ｈｆ衰变的γ射线。
Xinfeng Neutron isotope (185) Hf was first synthesized and identified by (n, 2p) reaction and rapid separation. The half-life of 3.5 ± 0.6min. In addition, a γ-ray belonging to ~ (185) Hf decay with an energy of 164.5 ± 0.5 keV and a half-life of 4.3 ± 0.9 min was also observed.
