Abstract

The D₂F radical has been studied by a combination of neutralized ion beam and charge stripping techniques. Neutrals formed by D₂F⁺/Na charge exchange are observed in metastable and dissociative states. The lifetime of metastable D₂F is greater than 0.4 μs. Metastability is not observed for HDF or H₂F. The dissociative state of D₂F releases about 1.9 eV of kinetic energy in its fragmentation products (DF + D). The vertical electron affinity of H₂F⁺ is calculated to be 6.6 ± 0.2 eV. The possibility of observing an emission continuum from electronically excited H₂F formed by H₂F⁺/K charge exchange is suggested. Similarities in the mass spectra of D₂F and the isoelectronic D₃O radical are indicated.
