The paper considers the class of Hamiltonian systems with two degrees of freedom. Based on the classical normal form. according to the rules of Born-Jordan and Weyl-MacCoy. its quantum analogs are constructed for which the eigenvalue problem is solved and approximate formulas for the energy spectrum are found. https://www.spidertattooz.com/Zenith-El-Primero-36-000-VpH-03-2150-400/
