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 inconsistencies 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.
