A proportional counter and a gamma scintillation spectrometer were used in studies of electromagnetic emission from Dy 9 (T = 44 days) prepared by tantalum target bombardment by 660-Mev protons. The spectrum of Dy/sup 159/ emission at 15 to 60 kev, taken by proportional counter with 130 mg cm/sup -2/ Al filter, is plotted. The non-converted gamma radiation with E = 58 kev is 6.1%; this agrees with the data on Gd/sup 159/ gamma decay. The intensity of the observed weak line at 350 kev was 5 x 10/sup -5/ quanta per decay. For transition to the first excited level of Tb (58 kev). considering L fluorescence as omega = 0.18 plus or minus 0.02, the ratio L/sub 1//K/sub 1/ is 0.56 and K is 0.32 plus or minus 0.08. (R.V.J.)
