Lead clusters: Different potentials, different structuresJonathan P. K. DoyeAbstractThe lowest-energy structures of lead clusters interacting via a Gupta potential are obtained for N<151. Structures based on Marks decahedra dominate at the larger sizes. These results are very different from those obtained previously using a lead glue potential, and the origins of the differences are related back to differences in the potential.The full paper is available from Science Direct and arXiv.org.
