The electronic structure of the 13-atom Rh cluster is studied with the structure model optimized by Estiu and Zerner using the discrete variational local-spin density-functional method. The magnetic moment per atom of the cluster is calculated to be 0.54 mu(B), in good agreement with experimental measurements (0.48 +/- 0.13)mu(B). It confirms our previous assumption that the structural distortion of the Rh-13 cluster from a perfect icosahedron to its ground state geometry decreases its magnetic moment and makes the theoretical calculation close to the experimental measurement.
