Abstract: 
We have measured electron impact ionization (EII) of the beryllium-like ion S12+. The use of an isotopically pure A = 33 beam of S12+ ions is established as a method to eliminate all metastable levels, including the extremely long-lived metastable level 2s2p P-3(0), which, for this isotope, decays by hyperfine-induced radiative transitions. The energy dependence and absolute size of the EII cross section were measured from the resulting pure ground-state population at energies from below the threshold at approximate to 652.2 eV up to 3000 eV. These data provide an experimental benchmark for theory.
