Spectroscopy of free sodium-ammonia clusters

Zero energy kinetic electron and mass analyzed threshold ionization spectroscopy of Na⋅(NH3)n (n=1, 2, and 4) complexes

“…30 The cluster source was similar to the design by Schulz's group. 31,32 A pulsed supersonic beam of pure ammonia ͑in the MATI experiment of Na•NH 3 ) or a mixture of ammonia and helium ͓in the ZEKE experiment of Na•͑NH 3 ) 2 ] was expanded into an effusive sodium beam generated from an oven perpendicular to the cluster beam. The thus formed Na•͑NH 3 ) n complexes were collimated by a skimmer 15 cm downstream.…”

“…The success of experimental studies of alkali complexes [27][28][29][30] is largely attributed to the development of the cluster source, either through the pickup design 31,32 or other approaches. 33, 34 Schulz's group measured the Na-N stretching and Na-NH 3 bending modes of the first electronically excited state of Na•NH 3 in a 1ϩ1Ј REMPI experiment.…”

Photoionization studies of free sodium ammonia clusters

“…Due to differences in the binding energies of the neutral and the ionic species the ionisation threshold is shifted towards lower energies compared to the Na atom. First results have been published in [12]. By studying the IP as a function of the cluster size one may hope to obtain information on the electronic structure of the cluster.…”
