Hydrogen-, Helium-, and Lithium-like Bound States in Classical and Quantum Plasmas

We study the effective interactions and mass action constants for pair triple associations in classical quantum plasmas. Avoiding double counting, we derive new expressions constants. The calculations resulted values that were substantially smaller than standard ones relevant temperature ranges by up to 50 percent. On this basis, determine pressure of H, He Li plasmas osmotic coefficient electrolytes with higher charges such as, e.g., seawater. Classical Coulomb systems show strong similarities. contributions low orders respect interaction e2 are suppressed thermal screening effects. weakly bound states, near continuum edge, reduced, replacing exponential functions cropped exponentials. consistent well-known extended limiting cases analyze examples including salts CaCl2 LaCl3, a model seawater multiple associations. In case systems, follow work Planck–Brillouin–Larkin H equation state (EoS) wide-density regions is obtained through concatenation EoS low-density region partial ionization degenerate plasmas, where all states dissolved Fermi, Hartree–Fock Wigner dominate.
