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/limited-time-Florida-Gators-NCAA-Mens-Highlights-Swimming-Trunks-p19075-limited-choice/
