摘要：

Frequency-dependent studies of second-harmonic generation from Ag(110) show resonant enhancement due to a transition between two surface electronic states. An increase in the nonlinear susceptibility, attributed to the coupling of the fundamental light with this transition, is proven by the energy dependence of the second-harmonic signal and by the observed selection rules dictated by the symmetry of the surface states.
