The abundance of the 83 Kr isotope, determined by ion mass analysis following three photon resonantfour photon ionization via the 5s’ [1/2] 1 state with a broadband laser is found to differ from the expectednatural value. This effect is discussed in terms of a change of the ionization response due to the decayof coherence in the intermediate state to its hyperfine structure coupling. The nonzero nuclear spinisotopes of Xe have not shown any effect of this type in three different ionization schemes under thepresent experimental conditions.
