ABSTRACT
We report the calculation of the effective mass (m*) of excess electrons injected in fluid methane as a function of number density (n). The calculation is performed within the framework of the Wigner–Seitz model for nonpolar fluids, using an accurate molecular potential which satisfactorily describes the scattering of low-energy electrons in the gas phase. Our calculated m*(n) values are found to decrease monotonically from the free-electron mass (m0) in the dilute gas limit to 0.72 m0 in the high-density liquid near the triple point. Comparison is made with available data in the literature.
