COMPUTER-SIMULATION OF THE ION ESCAPE FROM HIGH-ENERGY ELECTRON TRACKS IN NONPOLAR LIQUIDS

The number of ions escaping from recombination in high-energy electron tracks in saturated hydrocarbon liquids is calculated and compared wi th experimental results from the literature. The initial track structu re is obtained by bringing the details of the electron scattering into account. The number of positive ions and electrons that escape from c harge recombination is obtained from a computer simulation of the traj ectories of the positive ions and the electrons. The probability that the charges escape from each other is seen to change appreciably with the energy of the primary high-energy electron. The thermalization dis tance distribution of the electrons in the track is obtained by compar ing the calculated results with those from experiments. The influence of external electric fields on the escape of ions is considered.
