Two-center Coulomb problem with Calogero interaction

T. Hakobyan, A. Nersessian

Research output: Contribution to journalArticlepeer-review


We show that the Calogero-type perturbation preserves the integrability and partial separation of variables for the Stark–Coulomb and two-center Coulomb problems, and present the explicit expressions of their constants of motion. We reveal that this perturbation preserves the spectra of initial systems, but leads to the change of degree of degeneracy.
