COMPUTER-SIMULATIONS OF EXCESS ELECTRON-TRANSPORT IN NEON

The behavior of excess electrons in neon gas in a wide range of densities is investigated using molecular-dynamics simulations with a parameter-free interparticle potential. A realistic pseudopotential reproducing the measured electron-Ne low-energy scattering properties is used. A transition from quasi-free behavior to a localized regime where the electron is trapped in a bubblelike cavity is observed as the density is increased beyond a value that is close to the experimental one. The calculated electron mobilities in a wide range of densities are also found to be in reasonable agreement with the experimental data.
