  Below band gap formation of solvated electrons in neutral water clusters
using pump-probe photoelectron imaging is compared with recent data for liquid
water and with above band gap excitation studies in the liquid and clusters.
Similar relaxation times in the order of 200 fs and 1-2 ps are retrieved for
below and above band gap excitation, in both clusters and liquid. The
relaxation times independence from the generation process indicates that these
times are dominated by the solvent response, which is significantly slower than
the different solvated electron formation processes. The analysis of the
temporal evolution of the vertical electron binding energy and the electron
binding energy at half maximum suggests a dependence of the solvation time on
the binding energy.
