Quadratic algebra as a 'hidden' symmetry of the Hartmann potential

It is shown that operators, commuting with the Hamiltonian of the Hartmann potential form the quadratic Hahn algebra QH(3). The structure of this algebra and its finite-dimensional representations are described. An analysis of these representations is applied to obtain all the relevant physical results: energy spectrum, degree of degeneration and overlap functions.
