Abstract
From a phenomenological treatment of a correlation-induced metal-insulator transition at elevated temperatures, an interpretation of the behavior of the magnetic susceptibility of expanded fluid alkali metals is proposed. Renormalization of the Fermi temperature due to correlation is shown to play an essential role. An important conclusion is that the momentum distribution at the Fermi surface is quantitatively very different from that in jellium at the same density.
