AbstractThe drift velocities of radiation-induced excess electrons and positive charge carriers in liquid methane were measured at different electric field strengths and several temperatures. For the excess electrons the drift velocity increases up to 1.5 kV cm-1 proportional to the electric field strength and a mobility of (400±50) cm2 V-1 s-1 at T = 111 °K was obtained. Above 1.5 kV cm-1 the drift velocity varies with E½. The temperature coefficient of the mobility is negative. For the positive charge carriers the measurements were carried out up to electric field strengths of 50 kV cm-1 and the drift velocity remained proportional to the field giving a mobility of (2.5 ± 0.5) · 10-3 cm2 V-1 s-1 at 7 = 111 °K. The mobility increased with increasing temperature. The reaction of excess electrons with oxygen was also studied and a rate constant of 8.4 · 1011 l mole-1 s-1 was obtained.

Addition of nonelectronegative molecules (n-alkanes, alkenes, CO, CO2) to liquid argon, krypton, and xenon influences the drift velocity of excess electrons in an electric field. At high field strengths (104–105 V cm−1), where the electrons have mean energies exceeding kT, inelastic collisions with solute molecules lead to an increase of the drift velocity above the value of the pure solvent. Analysis of this effect yields the energy dependent product of collision cross section and mean fractional energy loss per collision.At low field strengths a decrease of the low field mobility with increasing solute concentration is observed from which the cross section for momentum transfer could be deduced. The influence of solutes on the low field mobility was also found in tetramethylsilane.
