Résumé :

A new method to calculate ionization properties of very dense correlated plasmas is proposed. In this early stage a mixture composed of hydrogen atoms in their ground state and unbounded protons and electrons is studied. All species are treated as classical point particles interacting through pseudo-potentials. As an effect of the strong correlation between hydrogen atoms it is found that the ionization can decrease as the temperature increases. All the correlation functions, excess chemical potentials and equilibrium ionization are evaluated in the HNC approximation. © 1991 IOP Publishing Ltd.
