Here we are posting the results of global optimizations for a variety of systems in a downloadable form. New results will be added once the corresponding papers have been accepted for publication. Various other results from ab initio studies and the ORIENT program may also be tabulated. Papers in which the results have appeared are indicated on the relevant pages; a suitable general citation for the CCD is The Cambridge Cluster Database, D. J. Wales, J. P. K. Doye, A. Dullweber, M. P. Hodges, F. Y. Naumkin F. Calvo, J. Hernández-Rojas and T. F. Middleton, URL http://www-wales.ch.cam.ac.uk/CCD.html. If you can improve on any of these lowest minima or wish to deposit results then please get in contact with us.
