Abstract

Light emission induced by inner-shell excitation of [Formula Presented] molecules has been investigated in the wavelength region [Formula Presented] Synchrotron radiation from the SuperACO storage ring in Orsay (France) has been used for the photoexcitation and a high-resolution secondary monochromator [Formula Presented] for the spectral analysis of the fluorescence light. Vibrationally resolved molecular [Formula Presented] [Formula Presented] transitions show clearly the coupling between the [Formula Presented] core excitation and the ionization of the [Formula Presented] valence electron. The main contribution to the fluorescence spectra stems from excited neutral and excited singly charged atoms produced by the dissociation of... (More)

Light emission induced by inner-shell excitation of [Formula Presented] molecules has been investigated in the wavelength region [Formula Presented] Synchrotron radiation from the SuperACO storage ring in Orsay (France) has been used for the photoexcitation and a high-resolution secondary monochromator [Formula Presented] for the spectral analysis of the fluorescence light. Vibrationally resolved molecular [Formula Presented] [Formula Presented] transitions show clearly the coupling between the [Formula Presented] core excitation and the ionization of the [Formula Presented] valence electron. The main contribution to the fluorescence spectra stems from excited neutral and excited singly charged atoms produced by the dissociation of highly excited molecular states. The singly ionized [Formula Presented] atoms are produced upon resonant [Formula Presented] excitation as well as upon excitation to the [Formula Presented] continuum resonance. Fluorescence transitions of the type [Formula Presented] [Formula Presented] as well as [Formula Presented] and [Formula Presented] have been analyzed. The neutral N fragment is found nearly exclusively after excitation of the [Formula Presented] resonance, and mainly radiative decay of the N [Formula Presented] excited states has been observed. The obtained experimental results represent additional and very detailed information on the final states of the molecular dissociation and provide a necessary basis for a theoretical treatment of the relaxation processes of inner-shell excited molecules.
