Abstract
We report analytic solutions of a recently discovered quasi-exactly solvable model consisting of two electrons, interacting via a Coulomb potential, but restricted to remain on the surface of a 𝒟-dimensional sphere. Polynomial solutions are found for the ground state, and for some higher (L ≤ 3) states. Kato cusp conditions and interdimensional degeneracies are discussed.
