  We have investigated the solvation dynamics and the genuine binding energy
and photoemission anisotropy of the solvated electron in neutral water clusters
with a combination of time-resolved photoelectron velocity map imaging and
electron scattering simulations. The dynamics was probed with a UV probe pulse
following above-band-gap excitation with a EUV pump pulse. The solvation
dynamics is completed within about 2 ps. Only a single band is observed in the
spectra, with no indication for isomers with distinct binding energies. Data
analysis with an electron scattering model reveals a genuine binding energy in
the range of 3.55-3.85 eV and a genuine anisotropy parameter in the range of
0.51-0.66 for the ground-state hydrated electron. All these observations
coincide with those for liquid bulk, which is rather unexpected for an average
cluster size of 300 molecules.
