Effective mass of an excess electron in fluids with high polarizability

The effective mass of an excess electron injected into a dense non-polar fluid with high polarizability is considered. The pseudopotential theory of electron interaction with a cellular fluid is used. Phase shifts of the p-scattering of an electron in a fluid are calculated. The Bardeen formula is used for the effective mass calculation. The density dependence of the effective mass in fluid xenon is compared with experimental data.
