Computer simulations of $C_6_0-Kr$ mixtures

Carbon $C_6_0$ fullerene mixed to $Kr$ rare gas at different concentrations and packing fractions has been simulated by microcanonical Molecular Dynamics (MD) in order to investigate the effect of the gas atoms on the structure and mobility of the $C_6_0$ molecules. A continnum representation for the $C_6_0$ molecule is assumed in order to use central model potentials for the three different interactions involved. A threshold value of the $Kr$ concentration is obtained for the $C_6_0$ spatial arrangement and mobility.
