Range-energy relations for 8.78 MeV alpha particles in ethyl alcohol and carbon tetrachloride in the liquid and vapour states have been determined experimentally using nuclear emulsion and scintillation counting techniques. The range in liquid alcohol was found to be greater than the value previously published. The stopping power for both liquids was found to be different from that of the corresponding vapour, and it is suggested that polarization of the absorbing medium is mainly responsible.
