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.
