Abstract

Unimolecular and collision-induced dissociation of

{Ar}_{2}^{+}

produced by electron-impact ionization of

{Ar}_{2}

were studied quantitatively with a double-focusing mass spectrometer. The occurrence of the metastable dissociation process

{Ar}_{2}^{+ *}

→

{Ar}^{+}

+ Ar is interpreted qualitatively in terms of potential-energy curves calculated recently using quantum-mechanical methods.
