Outline of Final Research Achievements

In order to elucidate dynamics of valence electrons in liquid metals, we carried out inelastic X-ray scattering experiments for investigating plasmon behaviors in liquid alkali metals. Plasmon excitation energy tends to decrease with decreasing fluid density, which is consistent with the prediction of the electron gas model. However, the value of the observed excitation energy takes a lower value than that of the model at a relatively high density region. This discrepancy is explained by the effect of structure of ionic system through the electron-ion interaction, which indicates that the structure of ionic system is crucial for understanding the collective behaviors of valence electrons even in the liquid state. On the other hand, in order to gain new information on the valence electronic state in liquid metals, we tried to develop a technique to construct electron response functions (in real time and real space) from the scattering spectra.
