ABSTRACT
Details the application of the perturbation theory to a pair of coupled oscillators with cubic anharmonicity. Large-order perturbation theory shown to be more efficient computationally than numerical diagonalization of the Hamiltonian; Quadratic Pade summation of the energy expansions yielding convergent results for the real and imaginary parts of resonance eigenvalues.
