Abstract
The use of many-body perturbation theory with time-dependent perturbations is reviewed and applied to a calculation of the frequency-dependent polarizability of atomic oxygen. The poles of are in reasonable agreement with the experimental excitation energies when diagrams beyond second order are included.
