Abstract

Recent mass spectroscopic studies of continuous cluster beams resulting from supersonic expansions of alkali metal vapor have led to the postulation of islands of enhanced thermodynamic stability among the clusters produced. We discuss the various assumptions being made in converting ion abundances measured in these mass spectra into information about neutral stabilities. In this connection a number of experiments are described which allow insight into unimolecular dissociation of alkali cluster ions and into neutral cluster growth.

    Evaporation may of course continue in the collisionless regime of the cluster beam. Typical cluster flight times between source and detector are on the order of 500 µs. An upper limit for cluster internal temperature is about 500 C. Consequently one would not expect to lose more than about one atom per cluster by evaporation — after collisions have ceasedGoogle Scholar

    An analogous number generating device applied to islands of enhanced stability in atomic nuclei was a great advance because interactive forces were poorly characterized. This is not the case for molecules containing alkali atoms, to which the full arsenal of quantum chemical methods can and should be appliedGoogle Scholar
