Electron Dissociative Attachment to NF2 Radicals

Measurements of discharge current in an electron beam sustained-discharge device have been used to determine the dissociative attachment rate constant of electrons to NF2 radicals.This was done by measuring the relative rate of electron attachment to NF2 compared to dilute molecular chlorine in a nitrogen buffer in separate experiments in the same device.A comparison of the steady-state current measured for these two different mixtures at identical total pressures and applied electric fields provides a relative measurement for the rate of disappearance of electrons.Since the attachment rate constant with molecular chlorine is well-known, rate constants for the fluoride radical could be determined.Values near 1.5 x 1E-9 cm³/s for average electron energies near 1 eV were obtained.
