Notes:
A molecular dynamic simulation study has been performed for a large-sized systemconsisting of 106 liquid metal Al atoms to deeply investigate the formation and magic numbercharacteristics of various cluster formed during solidification processes. It has been found that thenumbers of various types of cluster in the system obviously possess peak values, namely, magicnumbers. The first, second, third, .…,and tenth magic numbers are determined in turn in the order of13, 19, 25(27), 31(33), 38(40), 42(45), 48(51), 55(59), 61(65), 67,…( the numbers in the bracketsare the second peak values in the corresponding level of cluster). This magic number serial is ingood agreement with the experimental results obtained by Harris et al, and this method determiningthe magic numbers from the clusters according to the level of basic cluster can be used to afford aprimary scientific and reasonable explanation to experimental results
