We present an approach which allows the consistent treatment of bound states in the context of the dc conductivity in dense partially ionized noble gas plasmas. Besides electron-ion and electronelectron collisions, further collision mechanisms owing to neutral constituents are taken into account. Especially at low temperatures T ≈ 1eV, electron-atom collisions give a substantial contribution to the relevant correlation functions. We suggest an optical potential for the description of the electronatom scattering which is applicable for all noble gases. The electron-atom momentum-transfer cross section is in agreement with experimental scattering data. In addition the influence of the medium is analysed, the optical potential is advanced including screening effects. The position of the Ramsauer minimum is influenced by the plasma. Alternative approaches for the electron-atom potential are discussed. Calculations of the electrical conductivity are compared with experimental data.

Abstract. The extraction efficiency f for the photoelectrons emitted from a CsI photocathode into gaseous Xe-CH 4 and Ne-CH 4 mixtures is investigated by Monte Carlo simulation. The results are compared with earlier calculations in Ar-CH 4 mixtures and in the pure gases Xe, Ar, Ne and CH 4 . The calculations examine the dependence of f on the density-reduced electric field E/N in the 0.1-40 Td range, on the incident photon energy E ph in the 6.8-9.8 eV (183-127 nm) VUV range and on the mixture composition. Results calculated for irradiation of the photocathode with a Hg(Ar) lamp are compared with experimental measurements for this lamp. To test the electron scattering cross-sections used in the simulations, electron drift parameters in Xe, Ne and their mixtures with CH 4 are also presented and compared with available experimental data.

“…Except determinations of Hunter et al [42] and Schmidt et al [44], other experimental results of Koizumi et al [41], Pack et al [43] and Hayashi [45] are consistent within few percent accuracy (see Fig. 3) giving R-T minimum of (0.30-0.38)·10 −20 m 2 at 0.6-0.7 eV.…”

Modified effective range theory formulated as a Bayesian statistical model through the combination with Markov Chain Monte Carlo integration and fitting techniques is used to check the compatibility of different e − −Xe scattering data such as the total cross-sections, the momentum transfer cross-sections, and the differential cross-sections that were determined experimentally in the region of Ramsauer-Townsend minimum. On the basis of this predictive approach, the most probable value of the scattering length, (−6.51 ± 0.05)a 0 , is proposed. The present analysis suggests that the non-relativistic spinless effective range theory is suitable for the description of angular and energy dependencies of e − −Xe elastic scattering cross-sections below the threshold for first inelastic process.
