Title 



Pauli potential in terms of kinetic energy density and electron density in the leading Coulombic term of the nonrelativistic 1/Z expansion of spherical atomic ions

Abstract 



The Pauli potential VP in density functional theory is known to be the difference between the functional derivative of the singleparticle kinetic energy Ts[n] with respect to the electron density n and its von Weizsäcker counterpart. For the leading Coulombic term in the 1/Z expansion for spherical atomic ions, VP[n] is written in terms of the kinetic energy density plus n(r) and its loworder derivatives. For comparison, the example of an arbitrary number of closed shells with purely harmonic confinement is also treated.
