Abstract

We report on a study of carbon thirteen (¹³C) NMR spectra in a superconducting fulleride K₃C₆₀. It is found that the spectra are reproduced as powder patterns of anisotropic NMR shifts. By analyzing the NMR shifts, the ratio of isotropic hyperfine coupling (A_iso^spin) of conduction electrons to anisotropic one (A_ax^spin) is obtained experimentally for the first time (A_iso^spin/A_ax^spin = 0.78). The substantial isotropy is consistent with the crystal structure of the C₆₀ molecule. The contribution of carbon pπ-orbitals to A_ax^spin is found to be dominant.
