Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract The Bogolyubov hierarchy for equilibrium distribution functions is employed to define a chemical model for partially ionized hydrogen plasmas. The Helmholtz free energy is found in a self‐consistent manner beyond the linear mixing rule allowing one to determine not only the ionization equilibrium but the correlation functions as well. Particle interactions are effectively treated such that the charged and neutral components of the plasma are closely interrelated which results in short‐range order formation in the system of interest. The method proposed is an analog of the Debye‐Hückel theory of fully ionized gases and allows one to study both thermodynamics and transport phenomena in a partially ionized hydrogen.
