The effects of spin-orbit (SO) scattering on discrete electronic energy levels were studied in copper, silver, and gold particles using tunneling spectroscopy. The g-factors within a given sample exhibited mesoscopic fluctuations with distributions in good accord with random-matrix-theory predictions. The strength of spin-orbit scattering was found to increase with atomic number and vary between nanoparticles made of the same metal. Spin-orbit scattering rates in the nanoparticles were compared to weak localization measurements on larger samples.
