    Abstract

    We report the studies of the elasticity of O60 single crystals. For sublimed fcc crystals, Youngs modulus has an 8% jump at the first-order transition at 260 K. At 160 K there is a frequency-dependent elastic anomaly resulting from time dependent stress relaxation. Comparison with rotation rates seen in NMR suggests that the dynamics below 260 K is more complex than jumps between equivalent molecular configurations. Solvent grown monoclinic crystals have a second-order transition at 242 K, while the 160-K glass transition remains unchanged.
