Free-ion yields from 207Bi conversion electrons were measured as a function of applied electric field in an ionization chamber filled with tetramethylsilane(TMS) or tetramethylgermanium(TMG), which were purified by simple methods. Also, the mean thermalization length of electrons liberated in the liquid was calculated by fitting a Gaussian form for the distribution function. The total free-ion yield and thermalization length in TMS and TMG were obtained to be 3.1±0.3, 3.5±0.2 and 191±12Å, 173±16Å, respectively, including the impurity effect in liquid.
