Using a model of the fullerene C₆₀ molecule with carbon atoms uniformly distributed over its surface, the potential energy U(n) of a Xe atom in an octahedral void of C₆₀ is calculated. Within the framework of threedimen ...

The transmission high electron energy diffraction (THEED) technique was employed for studying the structure of the equimolar Ar–Kr alloy, in which the thermodynamics predicts the maximum feasibility of phase separation. ...
