Query: Calculation of Effective Coulomb Interaction for $Pr^{3+}$, $U^{4+}$,
  and $UPt_3$   In this paper, the Slater integrals for a screened Coulomb interaction of the
the Yukawa form are calculated and by fitting the Thomas-Fermi wavevector, good
agreement is obtained with experiment for the multiplet spectra of $Pr^{3+}$
and $U^{4+}$ ions. Moreover, a predicted multiplet spectrum for the heavy
fermion superconductor $UPt_3$ is shown with a calculated Coulomb U of 1.6 eV.
These effective Coulomb interactions, which are quite simple to calculate,
should be useful inputs to further many-body calculations in correlated
electron metals.
