Abstract
Coincidence studies between energy selected electrons and the 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. In this type of
measurement it is possible to correlate the ion fragmentation products, their
kinetic energy and electronic configuration with the hole configuration in the
singly or doubly charged molecular electronic states populated in the electronic
decay of the initial core hole excited state. This data produces a new insight
into the potential energy curves of the singly and doubly charged molecular ions
and into energy dissipation in highly excited molecular systems.
