We describe the pump-probe spectroscopy of atoms cooled in a 3D linlin
optical lattice. Our pump-probe configuration consists of two laser fields
detuned with respect to the lattice fields. This scheme allows to clearly
identify in the probe transmission spectrum the Brillouin and Raman resonances,
by studying their positions as functions of the angle between the pump and
probe beams. We describe these resonances in detail, and compare the
experimental results to the theoretical predictions. Our conclusions are
supported by transport-spectroscopy measurements, which allow to distinguish
between contributions to the light scattering from propagating and
non-propagating atoms.
