Abstract:

Positive silicon cluster ions prepared by laser vaporization in a supersonic beam and trapped in an ion cyclotron resonance cell were probed in chemisorption reactions with ethylene and ammonia. Clusters in the 36-51 atom size range were effectively annealed to unique structural forms by excitation with an XeCl excimer laser followed by cooling through infrared radiation and collisions with argon.
