The 7-ray spectrum from the decay of "'I was measured with smalland large-volume, high-resolution Ge(Li) detectors, and 116transitions were assigned in its decay. Selected regions of the conversion-electron spectrum were measured with an iron double-focusing spectrometer. The IC-conversion coefficient of the 772-keV transition that was measured relative to the X-conversion coefficient of the 662-keV transition in '"Ba was used to normalize the electron and y spectra to obtain the K-conversion coefficients of the 262., and. 1398. 6-keV transitions. Conversion coeKcients of additional transitions were obtained from electron intensities of other work. From these conversion coeKcients, each of the above transitions was assigned an bI1 and/or Z2 multipolarity.
