New data on quasi-elastic broadening from molten 7 Li 0 . 6 2 Na 0 . 3 8 confirm the earlier observation of critical narrowing at T=626K (T-T c =50K) and also show the expected behaviour at T=676K (T-T c =100K). Within the Q,T range studied and the limitations of statistics, no evidence was found for more than a single quasi-elastic component. While the predicted limiting behaviour within the critical region is approached, it is not fully reached. The experimental requirements for measurements truly within the critical region are discussed.
