Magnetotransport experiments on a semiconductor quantum ring in the Coulomb blockade regime are described. The measurements allow to extract the discrete energy levels of a realistic ring, which are found to agree well with theoretical expectations. The interaction effects important for our ring structure are analysed in detail. The experimentally observed charging energy can be quantitatively ...
