Neutron and X-ray diffraction from liquid Rb

Abstract

Motivated by the recent X-ray diffraction experiments by Matsuda, Tamura, and Inui (Phys. Rev. Letters 98, 096401 (2007)). on liquid Rb, it is stressed that important information about electron–ion and electron–electron correlations is embodied in a comparison of their X-ray data with the neutron observations of Franz, Freyland, Glaser, Hensel, and Schneider (J. Phys. (Paris) Colloq. 8, 194 (1980)). Electron diffraction experiments on liquid Rb would also be important, if feasible.

Keywords:
