Optical second-harmonic generation from a fixed-frequency laser at 1= 1064 nm has been used to monitor the adsorption of sulfur atoms on a Pd( 100) single-crystal surface. The signal observed was dominated by the contribution from the adsorbate atoms to the second-order susceptibility due to a reson
