摘要：

We study dissipation in a dilute Bose gas induced by the motion of a macro-scopic object. A blue-detuned laser beam focused on the center of a trapped gas of sodium atoms was scanned both above and below the BEC transition temperature. The measurements allow for a comparison between the heating rates for the superfluid and normal gas.
