FRACTALS IN ISOTROPIC SYSTEMS GENERATED WITH ATTRACTING SPHERES

Isotropic non-crystal fractal systems are generated using the techniqu e of simulated annealing and frozen Lennard-Jones fluids. From all nea rest neighbor bonds shorter than 1.15 sigma, a subset is selected rand omly with the probability p approximate to p(c). Afterwards. bond-perc olation clusters are searched for. Applying the box-counting method, t ile fractal dimension D is 2.58 +/- 0.015, and by fitting the slope of the static structure factor S(q), D is 2.40 +/- 0.02. Both values are close to that of a fractal system on a three-dimensional lattice.
