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.diegojavierfares.com/hot-super-Final-Audio-Sonorous-VI-Closed-Back-Over-Ear-Headphones-huge-savings/
