Atomic Ionization and Molecular Dissociation in a Hydrogen Gas within the Physical Picture



We study a hydrogen gas at low densities within the physical picture. Recombination processes leading to the formation of atoms and molecules are properly taken into account via the well-known Ebeling function and a new four-body partition function. Our method provides a reliable equation of state which covers the plasma, atomic and molecular phases (© 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
