Abstract
We simulate several methods which could be realized in the laboratory to pr obe the band excitation energies and the momentum distribution of a Bose-Ei nstein condensate inside an optical lattice. The values of the excitation e nergies obtained by the different methods agree within the accuracy of the simulation. The meaning of the results in terms of density and phase deform ations is tested by studying the relaxation of a phase-modulated condensate toward the ground state.
