Calculation of the electric microfield distribution in plasma

Summary form only given, as follows. Calculations for the probability field distribution in plasma generating a new expression for the Debye screening fields were proposed by Martin and Perez (1996). The method that we present is based mainly on the introduction of this adequate field in the calculus of the distribution. We find the spectral function F(k) carrying out the Fourier transform of the field which is numerically calculated for each representative value of the variable in k space and then fitting these data in order to get F(k). Thus, after the usual numerical integration on the wave number space, the field strength distribution is achieved. These approximation recovers the Holtsmark (1990) distribution in the limit of high temperature and/or small densities. This method is an improvement of previous procedures and simple to use.
