| Research Abstract |
Many-electron theory since Wigner's pioneering work has predicted that interacting electron gas suffers a negative compressibility and the static dielectric-function (DF) becomes negative when electron density is sufficiently reduced. However, a problem has remained unsolved as to whether the low-density electron gas with negative DF really exists or not. To clarify it we have measured Compton scattering for fluid rubidium with reducing density of electron gas. It was clearly observed that the Compton profile deviates from the free-electron model at the theoretically predicted electron-density.
