    "abstract": "We study the loss of spatial coherence in the extended wave function of\nfullerenes due to collisions with background gases. From the gradual\nsuppression of quantum interference with increasing gas pressure we are able to\nsupport quantitatively both the predictions of decoherence theory and our\npicture of the interaction process. We thus explore the practical limits of\nmatter wave interferometry at finite gas pressures and estimate the required\nexperimental vacuum conditions for interferometry with even larger objects.",
