Generalized ionization energies for full Coulomb atoms

We prove the energy part of the generalized ionization conjecture for full nonrelativistic Coulomb atoms with two electron spin states. The energy needed to remove m electrons is asymptotic to $a_{\mathrm{TF}}{m}^{7/3}$ whenever $m\to \infty$ and $Z/m\to \infty$, with the Thomas–Fermi constant in atomic units. We also obtain both conjectured iterated limits.
