We consider theories in which a kinetic-energy correction (h2322m) (=density) is added to the usual Thomas-Fermi term. A treatment based on the WKB method and expected to be valid for large r shows =1 here, as found experimentally. For small r, =1 is needed to give proper behavior of, but other arguments suggest that the Thomas-Fermi term be dropped here.
