Open-Shell Jellium Aromaticity in Metal Clusters

Abstract

The 2N2 + 2N + 1 with S = N + 1/2 rule represented the extension to open-shell spherical compounds of the 2(N + 1)2 Hirsch rule for spherical aromatic species. In this work, we provide evidence that the jellium model with its magic numbers can also be extended to open-shell half-filled systems
