Abstract
The formation and stability of the ordered structure LS13, composed of large and small monodispersed spherical particles L and S respectively in aqueous solutions, are investigated, the Brownian motion of particles with interparticle potential being simulated by the Monte Carlo method. The ordered structure is composed of an icosahedron of 12 particles S with a central particle S within a cube of particles L. It is found that formation of the ordered structure LS13 is successfully simulated once 13 particles S are distributed within a cube of particles L, and the conditions within which the ordered structure is stable are clarified.
