    "abstract": "We present an experimental study of Z-scan measurements of the nonlinear\nresponse of cold Cs atoms in a magneto-optical trap. Numerical simulations of\nthe Z-scan signal accounting for the nonuniform atomic density agree with\nexperimental results at large probe beam detunings. At small probe detunings a\nspatially varying radiation force modifies the Z-scan signal. We also show that\nthe measured scan is sensitive to the atomic polarization distribution.",
