✦ Synopsis

The decay of a N2 (v= 1) molecule within a N& cluster, causing subsequent loss of a "magic" number of molecules from the cluster, is modeled statistically. Up to clusters of size n = 19, the losses are explicable with a constant average binding energy of 660+30cm-'.

SIMS and FAB of solid N, generated large Nl, clusters (Nf -Nc4) which showed three types of metastable decay: (i) loss of a single N, molecule, assigned to ordinary ("thermal") metastability, (ii) nearly total disintegration, assigned to radiationless decay of an electronically excited state, and (i
