“…Examples have been found for model clusters interacting with longranged pair potentials, 1,2 and a wide variety of metal clusters. 3,4,5,6,7,8,9,10,11,12,13,14,15,16 For some of these examples, these disordered clusters appear at sizes between the magic numbers for the usual icosahedral, decahedral or face-centred-cubic (fcc) forms, that are typically most stable for materials that are close-packed for bulk; 10,13,14,15 i.e. the disordered structures are more stable than ordered structures with incomplete outer layers.…”
