Abstract

The diffusion coefficient of liquid lithium, which is expected to show large isotope effects because of its small atomic mass, was measured by the long capilary method under the microgravity due to the launch of the sixth TR-IA rocket. The detailed description is given for the procedure of the microgravity experiment for the very active element such as liquid Li. The smaller diffusion coefficient was obtained for 7Li in 6 Li compared with the case of 6Li in 7Li. These behaviours were discussed from the point of view of the hard sphere model.
