First order correction
WebPerturbation theory solves such a problem in two steps. First, obtain the eigenfunctions and eigenvalues of the unperturbed Hamiltonian, : (135) Second, correct these eigenvalues and/or eigenfunctions to account for the perturbation's influence. Perturbation theory gives these corrections as an infinite series of terms, which become smaller and ... http://electron6.phys.utk.edu/PhysicsProblems/QM/5-Time-independent%20approximations/non-deg%20osc.html

In time-independent perturbation theory, the perturbation Hamiltonian is static (i.e., possesses no time dependence). Time-independent perturbation theory was presented by Erwin Schrödinger in a 1926 paper, shortly after he produced his theories in wave mechanics. In this paper Schrödinger referred to earlier work of Lord Rayleigh, …
