| Abstract: | It is of practical importance for investigating the hyperfine structure of highly-lying energy levels of Uranium 235. We have measured the hyperfine structure of transition 0-16900-33625 1/cm, using double resonance method with two CW lasers The hyperfine structure constants A and B are also given. Thus a simple and precise method is provided for measuring highly-lying energy level structure of refractore and poisonous metals. |
