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

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.
