The solvation of electrons in aqueous solutions plays an important role in biological and chemical systems. Nonetheless, a fundamental understanding of its properties (e.g. solvation time, binding energies, solvation shells, and binding motifs) has yet to be fully attained. Here, we report new results for ammonia and water clusters investigating XUV ionization followed by electron recapture. The binding energies of the solvated electron were measured in a pump-probe scheme as a function of cluster size in which we found solvation times in the femtosecond to picosecond range.
