    • Spectroscopic features have been attributed to the Kondo resonance for systems other than a single, well-characterized magnetic impurity in a nonmagnetic host. See, for example, S. Gregory, Phys. Rev. Lett. 68, 2070 (1992); D. C. Ralph and R. A. Buhrman, ibid. 72, 3401 (1994); D. Goldhaber-Gordon et al., Nature 391, 156 (1998); E. L. Wolf, Principles of Electron Tunneling Microscopy (Oxford Univ. Press, New York, 1985). The pair-breaking effect of a single magnetic atom on a superconductor has also been observed [A. Yazdani, B. A. Jones, C. P. Lutz, M. F. Crommie, D. M. Eigler, Science 275, 1767 (1997)].

    • "Different tips" were obtained by changing the microscopic arrangement of the last few atoms on the STM tip through field emission and gentle collisions with the surface.

    • dI/dV traces taken with the tip displaced over the opposite side of the atom shown in Fig. 3 do not show as great a change in lineshape asymmetry. We attribute this to asymmetry in the particular STM tip used to acquire the data shown in Fig. 3.
