| Abstract: | Changes in the background intensities in giant Raman scattering spectra for silver surface in silver sulfate solutions, appeared at the varying of the silver galvanostatic deposition current near the silver electrode equilibrium potential, are measured. The connection between the silver adatom concentration and the intensity of the giant Raman scattering background allowed determining the absolute cross-section for the giant Raman scattering involving adatom-metal complexes: 1.02 × 10−27 cm2/adatom in sulfate solutions. |
