Interaction energy of elementary particles of an inductively coupled p
lasma was estimated with the Monte Carlo method used for canonical ens
emble. In the calculations, the Lennard-Jones, the Coulomb, and the io
n - polarisable atom interactions were considered. It was concluded th
at the kinetic energy amounts to about 90% of the plasma energy. It is
remarkable that the Coulomb energy values, given by the Debye-Huckel
and the Mean Spherical Approximation theories, are practically identic
al, and the results of the Monte Carlo calculations are in keeping wit
h these results as well.
