Atomic and molecular negative ions

Elliott H. Lieb

Research output: Chapter in Book/Report/Conference proceedingChapter


An upper bound is given for the maximum number, Nc, of negative particles (fermions or bosons or a mixture of both) of charge -e that can be bound to an atomic nucleus of charge + ze. If z is integral then Nc 2z. In particular, this is the first proof that H- is not stable. For a molecule, Nc 2Z + K - 1, where K is the number of atoms in the molecule and Z is the total nuclear charge.
