Abstract

We have measured the electronic energy spectra of Au nanoparticles of diameter 2-5 nm by tunnel spectroscopy, and found that the electron-in-a-box levels can be split into 2-10 energy levels, even in zero magnetic field. We propose that this splitting may result from spin multiplets in the presence of strong spin-orbit interaction. Relation to a theoretical model is discussed.
