  The visible photoabsorption spectrum and potential curves of ArN⁺

  摘要：

  The photoabsorption spectrum of ArN+ has been studied in the visible wavelength region by means of photofragment kinetic energy spectroscopy. The mass selected ions were accelerated to 25 keV and the ion beam was merged or crossed with a laser beam. The photoproducts Ar+/N and, weakly, Ar/N+ were observed as ArN+ was photodissociated with photons in the range 1.8–2.5 eV. This is the first observation of electronic transitions in ArN+. In order to interpret the results, potential energy curves of ArN+ were calculated with complete active space self-consistent field and multireference configuration interaction methods. The observed spectra are assigned to the A 3Π←X 3Σ−, C 3Σ−←X 3Σ− and C 3Σ−←A 3Π transitions. From these assignments a value of 2.16 eV for the dissociation energy of ArN+ is inferred.

  Observation of the formation of N⁺ and ArN⁺ in the collisions of Ar⁺(²P_3/2,1/2) with N₂

  摘要：

  Absolute total cross sections for the reactions, Ar+(2P3/2,1/2)+N2→N++N+Ar [reaction (1)] and ArN++N [reaction (2)], have been measured in the center-of-mass collision energy (Ec.m.) range of 6.2–123.5 eV. The appearance energy for the formation of N+ (Ec.m.=8.65±0.21 eV) is in agreement with the thermochemical threshold for reaction (1). The comparison of the collision energy dependence of the N+ cross section with the photoionization efficiency spectrum of N+ from N2 suggests that the predissociative multielectron states of N+2, C̃ 2Σ+u, F̃ 2Σ+g, G̃ 2Σ+g, and 2Σ+g (2σg)−1, which are responsible for the dissociative photoionization of N2, also play a role in the formation of N+ via reaction (1). Product ArN+ ions of reaction (2) are only observed in the Ec.m. range of 8.2–41.2 eV. At Ec.m. slightly above the thermochemical thresholds of reactions (1) and (2), the majority of ArN+ and N+ ions are scattered backward and forward with respect to the center-of-mass velocity of reactant Ar+, respectively. This observation is rationalized by a charge transfer predissociation mechanism which involves the formation of ArN+ and N+ ions via nearly collinear Ar+-N-N collision configurations at Ec.m. near the thresholds of reactions (1) and (2). At Ec.m.≥11 eV, more than 92% of the charge transfer product N+2 ions are found to be slow ions formed mostly by the long-range electron jump mechanism.
