>A prismatic beta spectrometer (with half-width line 0.04% and 1 x 10 mm source) was used for measurements of Ir/sup 192/, Eu/sup 152/ and Eu/sup 154/ conversion lines. The K-line energies for transitions 296, 308, and 316 kev in the Ir/sup 192/ spectrum were determined by comparing the positions of these lines with the lines I(E = 222.22 plus or minus 0.03 kev) and J(E = 234.61 plus or minus 0.03 kev). The energies of K-296 (E =217.52 plus or minus 0.03 kev), K-308 (E =230.00 plus or minus 0.03 kev), and K-316 (E = 238.06 plus or minus 0.03 kev) were determined. The energy of K-374 (E = 300.54 plus or minus 0.04 kev) was determined by measuring the energy distance between it and L/sub II/-316. Measurements were made of Ir/sup 192/ spectra for the energy difference in conversion lines from the Pt and Os subshells and from the Os K shell for transitions 201 and 205 kev. The prismatic BETA spectrometer (with half-width line 0.07%, and 1 x 10 mm source) was also used for measuring the energy distances between the lines L/sub II/-136.33 plus or minus 0.02 kev (conversion to Pt) in Ir/sup 194/, and M/sub III/-122 kev (conversion to Sm) in Eu/sup 152/ and Eu/sup 154/ spectra. The results are compared with published data. (R.V.J.)
