The structure factors of liquid tin were obtained in 2000 by neutron scattering experiments at temperatures of 1373 K, 1473 K, 1673 K and 1873 K in addition to 573 K, 773 K and 1073 K in 1999. Glassy (vitreous) carbon is revealed to be a good material for neutron scattering experiment at high temperatures. The absorption of neutron due to glassy carbon is as small as the case of silica glass container. Corrections of absorption and multiple scattering were performed. As a result, high temperature structure factors of liquid Sn were obtained accurately. In addition, by using this glassy carbon cell, the structure factor at 1273 K and 1673 K of liquid germanium was also obtained.
