SELF-CONSISTENT SCHEMES FOR THE CALCULATION OF IONIC STRUCTURES AND POPULATIONS IN DENSE-PLASMAS

We have generalized average-atom models so as to treat in a self-consistent way any given ionization stage present in a dense plasma mixture. The ionic structures with integer numbers of bound electrons as well as the free electron density are calculated quantically. They influence each other by the mean of thermally averaged potentials. Ionic structures with correct Coulombic interactions and equilibrium populations are obtained. Some results are presented for an aluminium plasma around solid density for temperatures between 50 and 500 eV.
