N2 - The properties of hot atomic microimpurities (57,58Co, 54Mn) in cyclotron metallic targets were investigated using the reaction 55Mn + α with emission Mossbauer spectroscopy employed to estimate the electronic state of the hot atoms. γ-Radiation self-absorption and sectioning methods were used to define the diffusion coefficients at 670-1200 K. The position of the 57Co atoms in the manganese lattice after irradiation and subsequent heating at the temperature of polymorphic α → β manganese (1000 K) transformations was established. Rapid diffusion of cobalt atoms at the polymorphic α → β manganese transformation was revealed. The radiochemical behaviour of 57,58Co, 54Mn after target dissolution was studied. The conclusion arrived at is that hot impurity atoms are a very effective tool in investigations of metallic cyclotron targets.
