Abstract
The interaction of two hydrogen impurities in jellium is calculated in the "overlapping-densities" approximation where the total displaced charge is the sum of two frozen single-ion screening densities. Using the fourth-order gradient expansion of the kinetic-energy functional, we obtain the results at various densities, corresponding to Al, Mg, and Na. The results provide an extension for the full treatment of the short-range proton-proton interaction to the asymptotic region where such exact calculation are as yet not available.Keywords
