The radiations of Co/sup 55/ were studied in a thin lens magnetic beta- ray spectrometer and in coincident scintillation spectrometers. By observation of the internal conversion lines and the unconverted gammaspectrum, gamma-rays of energies 1410, 937, 476, and 247 kev were resolved. No other gamma-ray of higher energy decaying with an 18-hr half-life could be observed after careful search of that region using a 41/2-in. diam and 4-in. thick NaI(Tl) crystal. The Fermi- Kurie analysis of the positron spectrum yielded three groups of positrons of maximum energies 1510 (51%), 1040 (45%), and 780 (4%) kev. These measurements revealed energy levels of the residual nucleus, Fe/sup 55/, at 937, 1411, and 1657 kev. (auth)
