Abstract

Weakly bound, multiply charged clusters are not detectable in mass spectra unless their size exceeds a well-defined critical size nc (z). Values for nc, with charge states up to z = 4, have been reported for van der Waals clusters and, in a few cases, for metal clusters, metal halide clusters and compound clusters. We review the experimental observation of multiply charged clusters and their critical sizes, including the apparently contradicting findings for metal clusters. Theoretical approaches towards a description of the “Coulomb explosion” are summarized. Recent progress in the size analysis of fragments from metastable decay of multiply charged clusters is described in detail.
