Comment on 'Electron structure of a dipole-bound anion confined in a spherical box' and 'Addendum to 'Electron structure of a dipole-bound anion confined in a spherical Box': The case of a finite dipole'

摘要

This Comment is motivated by some conceptual inconsistencies in the paper by Ronen [Phys. Rev. A 68, 012106 (2003)] and its Addendum [S. Ronen, Phys. Rev. A 68, 064101 (2003)]. While some of the inconsis-tencies are trivial—such as not distinguishing between anions and cations, and stating that polar molecules are made up of nuclei with positive and negative electric charges—the crucial one concerns the binding energy for an electron in a polar molecule, especially in the context of a confined molecular ion.
