✦ Synopsis
The classical potential energy surfaces for clusters of up to 25 atoms, interacting under two-body Lennard-.?ones forces, have been searched for global minima using the simulated annealing method. This is a Monte Carlo technique which simulates a process of slow cooling in order to avoid trapping in local minima. Two recently reported improvements over older work have been reproduced and a new minimum for 24 atoms has been found. The simulated annealing procedure yields low-lying energy states whose ~~bution depends on the cooling rate.
