摘要:

In liquids of spherical molecules (Ar, Kr, Xe, CH4) the mobility of thermal electrons passes through a maximum at a density near 1 × 1028molecule/m3. The ratioRmaxμnof the maximum mobility to the mobility in the gas phase, normalized for density, correlates strongly with the isotropic molecular polarizability α. The value ofRmaxμndecreases with decreasing sphericity of the molecules.
