“…The excluded volume concept is one of the popular simpler approximations to take the interaction of electrons with neutrals into account [31]. The fraction of volume occupied by atoms can be defined with the filling parameter η = 4/3πr 3 H n H , where r H is an atomic radius. The second virial coefficient is given for a system of hard spheres as…”

“…The equation of state describing fundamental characteristics of matter attracts significant attention of researchers from multiple disciplines. For instance, the calculation of thermodynamic properties of plasmas in the warm dense matter region is necessary to solve problems of high energy density physics [1] and to model the planetary and stellar interiors [2,3]. Correlations and bound state formation are of relevance since simple treatment of plasma using perturbation methods is not possible in this region.…”

The equation of state of partially ionized hydrogen plasma is considered with special focus on the contribution of e − H2 interaction. Within a cluster virial expansion, the Beth-Uhlenbeck formula is applied to infer the contribution of bound and scattering states to the temperature dependent second virial coefficient. The scattering states are calculated using the phase expansion method with the polarization interaction model that incorporates experimental data for the e − H2 scattering cross section. We present results for the scattering phase shifts, differential scattering cross sections, the second virial coefficient due to e − H2 interaction. The influence of this interaction on the composition of the partially ionized hydrogen plasma is confined to the parameter range where both the H2 and the free electron components are abundant.
