Number 70 (Story #3), March 5, 1992 by Phillip F. Schewe and Ben Stein BUCKYBALL ARTICLES were the most cited of all scientific topic areas in 1991. In a study conducted by the Institute for Scientific Information, Buckyball articles ranked 1st, 3rd, 4th, and 9th among the top ten most-cited science stories. These papers included those on C-60 superconductivity (#1: A.F. Hebard et al., Nature, 18 April 1991), conducting films of C-60 and C-70 (#3: R.C. Haddon, Nature 28 March 1991), and crystal structure of C-60 (J.M. Hawkins et al., Science, 12 April 1991). Several other buckyball articles published before 1991, such as Kratschmer et al., Nature, 27 Sept. 1990, continue to be quite popular. (Science Watch, Jan. 1992.)
