Ab-initio electron - liquid phase xenon fully differential cross-sections for
electrons scattering in liquid xenon are developed from a solution of the
Dirac-Fock scattering equations, using a recently developed framework [1] which
considers multipole polarizabilities, a non-local treatment of exchange, and
screening and coherent scattering effects. A multi-term solution of Boltzmann's
equation accounting for the full anisotropic nature of the differential
cross-section is used to calculate transport properties of excess electrons in
liquid xenon. The results were found to agree to within 25% of the measured
mobilities and characteristic energies over the reduced field range of 10^{-4}
to 1 Td. The accuracies are comparable to those achieved in the gas phase. A
simple model, informed by highly accurate gas-phase cross-sections, is
presented to transform highly accurate gas-phase cross-sections to improve the
liquid cross-sections, which was found to enhance the accuracy of the transport
coefficient calculations.Comment: 26 pages, 9 figures. arXiv admin note: text overlap with
