A Study of Photoionosation Mass Spectrometry of Nitrous Oxide

The absolute optical oscillator strengths density spectrum and photoionization mass spectrometry of nitrous oxide in the energy region of 7.8~24.5eV have been measured at an im-pact energy of 2500eV with the FWHM 200meV. Values of the partial photoionization oscillator strengths density of N2O+, NO+, O+, N2+and N+are reported and values of the oscillator strengths density for neutral dissociation in the energy region of 13.0~21.0eV are reported for the first time. The competition among different decay channels of the superexcited states of ni-trous oxide is expatiated.
