We measure the inelastic scattering cross section between ultracold rubidium atoms and carbon nanotubes. The measurement is done by spatially overlapping ultracold thermal clouds and Bose-Einstein condensates with a single carbon nanotube and recording the atom loss. From the data we derive the velocity dependent scattering radius of the nanotube.
