| Abstract: | The magnitude of an electric dipole moment must be larger or equal to a certain value to support bound states. Such critical dipole moment, pcrit, has been calculated in 2 and 3 dimensions and has been suggested that its calculation in one dimension cannot be possible. We evaluate pcrit in one dimension showing that the previous suggestion is untenable. |
