Abstract
Featureless abundance distributions are found for sodium atomic clusters in a cold He flowstream by laser ablation, demonstrating that the "magic number" ledges observed previously from oven-beam experiments are caused by high cluster temperatures. The utility of the cold pulsed beams indicated here by experiments on photoionization and photofragmentation properties, including ionization potential estimates for n as large as 137. Electronic and chemical measurements on cold alkali metal clusters in beams or flowing gases will permit critical tests of the electronic shell model.
