Surveying a complex potential energy landscape: Overcoming broken ergodicity using basin-sampling

P(Q6,T) for LJ75 and four structures: the global minimum (decahedron, Q6=0.31), the lowest minima based upon icosahedral packing with anti-Mackay and Mackay overlayers (Q6=0.02 and 0.15, respectively), and a minimum associated with the liquid-like phase (Q6=0.10).118
