  bibo_abstract:
  - As the nuclear charge Z is continuously decreased an N-electron atom undergoes
    a binding-unbinding transition. We investigate whether the electrons remain bound
    and whether the radius of the system stays finite as the critical value Zc is
    approached. Existence of a ground state at Zc is shown under the condition Zc
    < N-K, where K is the maximal number of electrons that can be removed at Zc
    without changing the energy.@eng
