摘要：

Mass spectra are reported for large sodium clusters warmed by a continuous laser beam prior to ionization. During the 1 ms warming period, the clusters lose more than 10% of their mass by single-atom evaporation. The resulting size distribution reveals what appears to be electronic shell structure for clusters containing up to 2500 atoms.
