The structures of P-8 and P-9 clusters

Full-potential linear-muffin-tin-orbital molecular-dynamics (FP-LMTO MD) ca lculations have been performed to investigate the structures and energies o f P-8, and P-9 clusters. We get fourteen stable structures for P-8 and fift een stable structures for P-9. The results confirm that "cuneane" structure is the most stable isomer of P-8 clusters. However, the distortion of a D- 3h Prism, which has not been reported so far, is the most stable among the fifteen P-9 isomers.
