Calculation of the effective mass of excess electrons in fluid argon, krypton, and xenon

Abstract

The effective mass (m■) of excess electrons in fluid argon, krypton, and xenon is calculated as a function of fluid density (n). The calculations are carried out within the framework of the Wigner–Seitz model for nonpolar fluids, using high-precision pseudopotentials to represent the electron–rare-gas atom interactions. The calculated electron effective masses are compared to available m■(n) data estimated from experiment.
