The distribution coefficients of Am and Ce were measured in the LiCl-KCl/Ga system at 773 K. By using ZrCl$$_4$$ as the oxide ion scavenger in order to avoid the formation of such oxychlorides as CeO$$^+$$ and AmO$$^+$$, the effect of oxide ion concentration was well controlled on the distribution coefficients of Am and Ce. The separation factor between Am and Ce was then obtained to be about 100. By comparing the present value with the other experimental and the predicted ones, it was confirmed that solvent metals were ordered from the most selective to the less selective one as Al$$>$$Ga$$>$$Bi$$>$$Cd.
