Evaluation of Critical Parameters of Neon Isotopes for Comparative Analysis of Various Methods for Separating Them

Values of critical parameters of neon isotopes 20Ne and 22Ne are calculated. Approximate constants of the van-der-Waals, Berthelot, Dieterici I, and Redlich–Kwong equations of state are obtained. The data allow the adsorption isotherms for the neon isotopes on different adsorbents to be estimated by calculations.
