    "abstract": "We report on cw measurements of probe beam absorption and four-wave-mixing\nspectra in a $^{85}$Rb magneto-optical trap taken while the trap is in\noperation. The trapping beams are used as pump light. We concentrate on the\ncentral feature of the spectra at small pump-probe detuning and attribute its\nnarrow resonant structures to the superposition of Raman transitions between\nlight-shifted sublevels of the ground atomic state and to atomic recoil\nprocesses. These two contributions have different dependencies on trap\nparameters and we show that the former is inhomogeneously broadened. The strong\ndependence of the spectra on the probe-beam polarization indicates the\nexistence of large optical anisotropy of the cold-atom sample, which is\nattributed to the recoil effects. We point out that the recoil-induced\nresonances can be isolated from other contributions, making pump-probe\nspectroscopy a highly sensitive diagnostic tool for atoms in a working MOT.",
