Monte-Carlo calculations of microfield distributions in a plasma

An electrical distribution function computation has been made with a Monte-Carlo program containing a serrated potential, and is presented in this report. The microfield created on one ion by all the others ions is thus obtained, taking the notching by electrons and the position correlations of a great number of ions in account. Several numerical approximations are possible: those used by De Witt, Hubbard and Hansen, but only for thermodynamical calculations and the spherical mean one, introduced by Paris, that has been widened to serrated potentials this last method reduces the calculation time and memory overcrowding. Microfield distributions calculated by these different approximations are compared
