Pseudopotential Approach to the Thermodynamic Functions of a Dense Hydrogen‐Like Plasma

Pseudopotential approach allows to include the quantum mechanical effects and eliminates the short range classical divergence. At high temperature, when the De Broglie wavelength for a pair of particles, , is larger than the Landau length, L ij , we have to introduce quantum mechanics. For two point‐charge particles without screening, we study the pseudopotential, u ij (r), numerically. We give expansions of the pair radial distribution function, g ij ( r ) ( = exp(—βu ij ( r ))) in increasing powers of . For a pair of electrons, exchange effects are taken into account. With these pseudopotentials, we study a dense multicomponent plasma using classical methods and we evaluate thermodynamic functions.
