Abstract
At 296 K the electron mobility decreased in the liquids n-hexane>n-decane>n-dodecane >n-tetradecane in accord with the two state model of electron transport (e−il⇄e−qf); the percolation model was inadequate. The temperature dependences were determined for n-decane, n-dodecane, n-tetradecane to T>450 K. Free ion yields were also measured. At a given temperature Gofi was the same in all these liquids to within ±4%. The density-normalized thermalization ranges of secondary electrons, estimated from the extended Onsager model, were bGPd =(49±1)10−6 kg/m2 under all conditions.
