Abstract
The investigation of the ion dynamics in the liquid alloy K52Cs48. which has the same electron density as Rb, was carried out by neutron inelastic scattering. Well defined collective excitations were observed up to the maximum value of momentum transfer of the experiment. A scaling of the dispersion relation data was found to hold between K-Cs alloys, Rb and Cs. The suggested scaring points out the key role of the conduction electron density in the collective dynamics of alkali metals.File in questo prodotto:
