The ionization potential distribution of (CH3)2S doped in fluid krypton and xenon has been determined by means of field ionization in wide density ranges. These distributions are simulated by convoluting the field spectrum of pure (CH3)2S with the calculated polarization energy distribution of the dopant ion in the media. The density dependence of the conduction-band energy of excess electrons (V0) in the fluids is obtained from the energy shift between the experimental and simulated spectra. The resulting V0 values are compared with previous experimental results and several theoretical calculations. © 1997 American Institute of Physics.
