Abstract :
The double photoionization of N2O molecules, in the 28–40 eV energy range, has been studied by synchrotron radiation. In the whole energy range, dissociative ionization producing N+ + NO+ or N 2 + + O + has been observed. Below ∼35.5 eV, these two processes involve the formation of some autoionizing states. In the range between ∼35.5 and ∼38.5 eV the two processes occur instead by a direct coulomb explosion of the N2O2+ dication. Above ∼38.5 eV the dissociation leading to NO+ + N+ is also promoted by the formation of a dication metastable state which decays by fluorescence to the ground state and then dissociates.
