[en] Elastic scattering of deuterons off carbon nuclei is studied in the Glauber model. Fits to the 650 MeV elastic scattering data are attempted using, firstly, nucleon-nucleon data as input and the α-particle model of the carbon nucleus, and, secondly, deuteron-proton scattering data as input with both an independent particle and an α-particle description of the carbon nucleus. In all these cases the best fits are qualitatively the same as those obtained in a recent calculation using nucleon-nucleon data as input with an independent particle model of the nucleus
