Two nonperturbative approaches are used to calculate the total cross sections for the double photoionization of Li from its ground and first excited states. From the ground state, both the time-dependent close coupling and R matrix with pseudostate approaches find reasonable agreement with experimental data, and from the first excited state (where no measurements are available), the two approaches are also in reasonable agreement.
