利用14MeV中子轰击天然钨靶,通过^180,182,183,184,186W(n,2pxn)反应,产生铪的放射性同位素,以γ(X)谱学方法鉴别出铪,观测到了能量为75.2keV和88.7keV的2条新1射线,测定其半衰期为(3.6±0.6)min。
By irradiation of tungsten with 14 MeV neutrons, hafnium radioactive isotopes have been produced through the ^180,182,183,184,186W(n,2pxn) reaction. Hf has been identified with 7 (X) spectroscopic method. The two new 7 rays of 75.2 keV and 88.7 keV were observed. And their half-life has been determined to be 3.6 ± 0. 6 min.
