The direct scanning tunneling microscopy (STM) imaging of the isolated discandium fullerenes (Sc[sub 2] C[sub 84]) on silicon clean surfaces in an ultrahigh-vacuum environment has been reported for the first time. The STM images reveal nearly spherical Sc[sub 2] C[sub 84] fullerenes, spaced 11.7 A apart and stacked in close-packed arrays at room temperature. The results present the first direct evidence that the scandium atoms are trapped inside the C[sub 84] cage. 21 refs., 4 figs.
