Abstract

The Coulomb explosion of metastable SF ₄ ²⁺ ion formed by electron impact on SF ₆ is demonstrated. The mass-analyzed ion kinetic energy (MIKE) scan technique is used for the demonstration purpose. It is found that SF ₃ ⁺ and F ⁺ ions are formed with an average kinetic-energy release of about 5 eV. The results show that the relative cross section for the process as a function of energy has a threshold of about 45.5 eV.
