Because ferrooyanide has no magnetic moment, it was investigated as an absorber in studies of the Mossbaner effect with Fe/sup 57/ as source. The source was soft iron plated with Co/sup 57/ and annealed; the 14.4-kev gamma ray from the vibrated source was passed through a sodium ferrocyanide absorber at 80 and 300 deg K and then analyzed. The% change in transmission is plotted vs. velocity for the ferrocyanide absorber at 80 deg K and for a soft iron abaorber at 300 deg K for comparison. It is concluded that the inner magnetic field in ferrocyanide is less than 10% of that in soft iron. The peaks for ferrocyanide at 300 deg K fall in the same places as those at 80 deg K but with amplitudes reduced by 60 plus or minus 10%. It is calculated that a ferrooyanide source at room temperature will emit about 40% of the 14.4-kev gamma ray without energy change as compared with 60% for soft iron. (D.L.C.)
