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 Nþ 2 þ Oþ 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
