Abstract
IT was shown by Fermi and co-workers1 that the activity induced in iron by neutron bombardment is due to an isotope of manganese. The isolation of an active iron isotope has not been reported. By means of the sensitive tube counter outfit2 in this institute, it was found that active iron can be isolated from cobalt which has been irradiated with neutrons, whereas irradiated iron after removal of manganese was found to be inactive.
