Tabulated data enumerate the energies of gamma transitions identified in studies of conversion electron spectra. Intensities of gamma rays are selected so that the internal conversion coefficients of the K and L shells for 80 kev gamma transitions correspond to theoretical transitions of the E2 type. The multiplicity of various transitions on the K shell was determined by comparing coefficients of internal conversion with theoretical data. The experimental magnitude of alpha /sub K/ transitions at 183.9 kev coincide with the theoretical data for E2 type transitions, The multiplicity of 214.1 kev transitions is defined as single sign E1. The transitions of 459 and 596 kev are probably of the same type, The coefficients of internal conversion transitions 1181, 1277, 1350, and 1878 kev satistactorily coincide with the theoretical E2 type. The multiplicity of these transitions is either E2 or M1 + E2. The obtained data verified the Tm/sup 166/ decay scheme. The first and second rotational level lines of Eri/sup 166/ are presented. Further measurements of conversion electron energies and experiments with coincidences are suggested in order to clarify the sequences of Er/sup 166/ high excitation states and their quantum characteristics.
