摘要：

Lead-cluster ions, Pb+n with n≤ 12, have been neutralized in sodium vapor under near-resonant conditions. Absolute charge exchange cross sections were measured as a function of cluster size and are on the order of 40 Å2 for n≥4. Possible fragmentation of the clusters associated with charge transfer was examined by translational spectroscopy. No indication of fragmentation was found. It is conclude that neutral lead-cluster beams with ultra-narrow size distribution are produced. © 1990.
