    Notes: Abstract Photoabsorption spectra of free LinH clusters have been recorded for n=2 to 9. Clusters are produced by coexpansion of 10–100 mbars of lithium vapor and 2–4 bars of a 98 % / 2 % mixture of argon with hydrogen. Two photon ionization was used to study the X ← B system of Li2H while beam depletion spectroscopy was used to measure the absorption cross sections of larger clusters. Most observations may be interpreted by the localization of one electron on the hydrogen bonding in agreement with ionization potential measurements.

    Static electric dipole polarizabilities of alkali clusters (1999)

    Notes: Abstract. We have measured the static dipole polarizability of lithium and sodium clusters (n=1-22). Values measured for sodium are in agreement with previous experiments. While the polarizability per atom for sodium clusters decreases slowly as a function of the cluster size, a sharp decrease between sizes 1 and 4 is observed for lithium clusters. Experimental values are compared to Density Functional Theory (DFT/PW91) calculations. The size evolutions for sodium and lithium cluster polarizabilities are well reproduced by our calculations. The sharp decrease observed for small lithium clusters is discussed in terms of electronic density.
