Electron-ion recombination in dense rare gases: Energy diffusion theory vssimulation

An analytical method using the concept of diffusion in energy space is appl ied to calculate the electron-ion recombination rate constant and the elect ron escape probability in dense gaseous argon and krypton. The results are compared with the respective data obtained from computer simulations. The d iscrepancies between the two methods are found to be relatively small. The applicability of the energy diffusion approach is discussed. (C) 2000 Ameri can Institute of Physics. [S0021-9606(00)01708-6].
