Abstract

Coincidence studies between Auger electrons and ions produced in the decay of a core hole excited state in free molecules reveal the individual pathways of soft x-ray induced fragmentation processes. We are able to identify the electronic configuration leading to stable or unstable ionic states. Measuring the kinetic energy of the ions, we also get data about the potential energy curves of the electronic states populated in the Auger decay of the core hole.

    One exception to this has been observed to date. In HBr the creation of a Br 3d core hole was shown to directly lead to a dissociative state; P. Morin and I. Nenner, Phys. Rev. Lett. 56. 1913 (1986).Google Scholar
