Abstract
We show that the use of the interelectronic vector as adiabatic axis allows two-electron states of atoms to be described in terms of molecular orbitals. The associated potential curves can be obtained by scaling calculations on the molecular ion and show for doubly excited states a strong similarity to adiabatic curves obtained from an analysis in hyperspherical coordinates. We associate a definite molecular symmetry with each two-electron state.
