Popis:	The MBr/sub 3/ + M phase diagrams for La, Ce, and Pr are presented. Lanthanum and Ce exhibit simple solutions of metal, with 14 and 12 mole% dissolved in eutectic temperatures of 728 and 687 un. Concent 85% C, respectively. The compound PrBr/sub 2.38/ is found, melting incongruently to a solution of 16% Pr in PrBr/sub 3/ and Pr(s) at 601 un. Concent 85% . For Pr the cryoscopic behavior of dilute solutions of metal is consistent with the primary formation of the Pr/sup 2+/ solute. But with La and Ce the results are anomalous, as the cryoscopic analyses indicate 1.6 to 1.7 and 2.0 new particles (cation basis) per metal dissolved instead of st run. Concent 3. (auth)
