Description
Final product states of Ne2+ dissociative recombination were studied using time-of-flight spectroscopy to determine the kinetic energies released. The dissociative recombination occurred in a sustained discharge in the presence of a variable magnetic field and discharge voltage, at pressures of 5 endash 15 mTorr. Under different conditions various excited states were observed ranging from the lowest 3s metastable states to higher Rydberg states within 0.00054 eV of the dissociation limit. From their narrow widths, it is deduced that these higher states arose from Ne2+ ions with subthermal energies. From two of these narrow distributions, we obtain an improved value for the dissociation limit D0(Ne2+)=1.26±0.02eV. copyright 1997 The American Physical Society
