摘要：

It is an intrinsic question whether or not the small metallic nanoclusters might have a structure different from the bulk structure. We observed a face-centered-cubic (fcc) structure for small Cr and Mo nanoclusters rather than a bulk body-centered-cubic (bcc) structure. We determined the critical cluster size n(crit) to be 490+/-100 for metallic Cr nanoclusters and the range of the n(crit) to be 1460-3900 for metallic Mo nanoclusters at which a structural transition from the fee structure into the bulk bcc structure occurred.
