Abstract :
Summary form only given, as follows. We show how the electrostatic fluctuations can be calculated in plasmas where both the ion and electron distributions are described by simple pole expansions, in 1D and isotropic 3D plasmas. We present calculations of the spectral density of the fluctuations as a function of frequency and wavenumber. For comparison with measurements we integrate over wave number to obtain the spectral density as a function of frequency only.
