X-ray diffraction for liquid Rb and liquid Na has been measured under pressure up to 6 GPa using synchrotron radiation. Volume dependences of static structure factor S (Q) and pair distribution function g (r) were obtained to the volume range v (=V/V<SUB>0</SUB>) of 0. 52 for liquid Rb and to v of 0. 73 for liquid Na to investigate the effect of the electronic change on the structure of liquid metals. With increasing pressure, the peaks of S (Q) of both liquid Rb and liquid Na shift towards higher Q, and the heights of the first peak increase. These volume dependences of the structural data are compared with those for other metals under pressure and expanded fluids.
