Perturbation theory calculations for an electron-ion system.
- James D.
In previous work, we have calculated the expansion of the pressure P of an electron-ion system. This expansion is in powers of the electron charge e. We extended the expansion by adding the e{sup 4} term and gave results for general ion charge Z and general de Broglie density {zeta}. In our present work we now have obtained the expansions for the internal energy U, and the potential and kinetic energy. In addition we have obtained expansions for several, dimensionless, thermodynamic quantities which depend on derivatives of the aforementioned quantities. They are the Griineisen's parameter, {Lambda} = {Omega}({partial_derivative}p/{partial_derivative}U)|{sub {Omega}} where {Omega} is the volume, the adiabatic exponent {gamma} = {Lambda} = (T/P)({partial_derivative}P/{partial_derivative}T)|{sub {Omega}}-({Omega}/P)({partial_derivative}P/{partial_derivative}{Omega}){sub T} where T is the temperature, and the dimensionless specific heat g = P{Omega}/[T({partial_derivative}U/{partial_derivative}T)|{sub {Omega}}]. These quantities are of interest in the hydrodynamic behavior of fluids, and, in particular, shock and release wave features.
