Abstract: The Miissbauer effect in 151Eu is used to examine the mixed hexammines Eu x Ca l _ x (NH 3 )6' with x = 0.012 and 0.092, and comparison is made to the apparent lack of conduction electron effects on the europium ionic and nuclear properties in Eu(NH 3 )6' In zero external magnetic field, very broad lines are seen, indicative of weakened dipolar spin relaxation. For the 1.2% Eu sample, the single Lorentzian linewidth at 4.2 K is the broadest yet seen, 19 mm/sec, with little structure evident. The linewidth dec…
