In the planar limit it results in the anisotropic oscillator perturbed by specific forth order potential. The origin of this potential is quite simple but important. When we transform the oscillator in the Coulomb system, this potential results in the Stark term. Hence, from the initial system we get the integrable model for the study of Stark effect in the Coulomb system on sphere and hiperboloid.
