In our contribution we focus on the measurement of the efficiency of intermolecular coulombic decay (ICD) in neon clusters and in water clusters.
Quite uniquely, our setup allows the quantitative determination of the efficiency of ICD relative to other competing channels. We introduce this technique and discuss the ICD efficiency after inner valence ionization in neon clusters, in water clusters and in clusters of heavy water.
By comparing the ICD efficiency in water and heavy water we can estimate the influence of the dynamics of the two systems on the ICD efficiency. Using these results we can obtain limits on the decay rate of ICD in large systems, i.e. water clusters with a mean size of N = <60>.
