Abstract  

Ingrowth of60Co radioactivity in an iron sample irradiated in a nuclear reactor has been measured for determination of formation cross section of60Fe in the59Fe(n, )60Fe reaction with reactor neutrons. After 5 years cooling, the irradiated iron was purified from60Co and other radioactive nuclides by an anion exchange separation method and isopropyl ether extraction in hydrochloric acid. The amount of60Co ingrowth was measured by -spectrometry using a Ge-detector coupled to a multichannel pulse height analyzer 4 years after the purification of iron. Neutron flux of the irradiation position was calculated from the amount of55Fe produced. The observed value of 12.5±2.8 barn is slightly greater than reported value for burnup cross section of59Fe(n, x)X, where x refers , , d, p and 2n, and X is any nuclide produced by the above reactions.
