摘要：

Metallocarbon dusters of the type YmCn(m = 1-3), ScmCn (m = 1-3), and CamCn (m = 1,2) are produced via the laser-vaporization cluster beam technique. The observed features of the intensity distribution of positive ions in mass spectra suggest that M@C-n (M = Y, Sc, and Ca; n greater than or equal to 44) and M-2@C-n [M = Y (n greater than or equal to 62) and Sc (n greater than or equal to 52)] clusters have endohedral mono- and di-metallofullerene structures, respectively. The mass spectral evidence is also consistent with the idea that Y2Cn (29 less than or equal to n less than or equal to 59) and Sc2Cn (29 less than or equal to n less than or equal to 49) clusters containing an odd number of carbon atoms form "networked" endohedral structures such as Y@(YCn) and Sc@(ScCn).
