Abstract : Gamma radiations following the radioactive decay of 56Co and 56Mn have been measured with Ge(Li) detectors. From 56Co, previously unobserved gamma rays of energies 2213.0 and 3598.7 keV have been identified while those of energies 1810.9, 1963.4 and 2112.8 keV are confirmed. Gamma-gamma coincidence measurements have been carried out with Ge(Li) and NaI(Tl) detectors. Gamma spectra in coincidence with the 846.6, 1037.6 and 1238.0 keV gamma rays have been measured, and a number of gamma-gamma cascades identified. From 56Mn, a previously unreported gamma ray of energy 3119.3 keV has been observed. A revised decay scheme is presented together with a discussion of the information that the new data provide on level energies, spins and parities. (Author)
