Abstract
Cross sections for the excitation of the ν1 = 0 and 1 vibrational levels of the electronically excited N2(C,ν′) product state have been measured, for collision energies in the range 85 ⩽ E(meV) 115, using the short-lived laser-excited Kr{(4p)55p;3D3} atoms as projectile. The cross sections Qν′ = 10.0 Å2 for ν′ = 0 and 7.2 Å2 for ν′ = 1 for this slightly exothermic process are interpreted in terms of a Landau-Zener model, with the ionic Kr+ + N2− state as an intermediate which crosses both the initial and final state. The crossing parameters are in good agreement with the results obtained for the similar but strongly endothermic process for the Kr{(4p)55s;3P0,3P2} + N2 systems, investigated by Vredenbregt et al. [Chem. Phys. 145 (1990) 267] in the superthermal energy range.
