Abstract

We consider heavy neutral atoms of atomic number ZZ modeled with kinetic energy (c2p2+c4)1/2c2(c^2p^2+c^4)^{1/2}-c^2 used already by Chandrasekhar. We study the behavior of the one-particle ground state density on the length scale Z1Z^{-1} in the limit Z,cZ,c\to\infty keeping Z/cZ/c fixed. We give a short proof of a recent result by the authors and Barry Simon showing the convergence of the density to the relativistic hydrogenic density on this scale.
