FAST NEUTRON BOMBARDMENT OF ⁶⁴Ni AND DECAY OF ⁶⁴Co

PRASIT CHAROENKWAN

Summary: Bombardment of nickel enriched in ⁶⁴Ni with 14.3-MeV neutrons from the neutron generator produce three activities with the half-lives of 26 1 s, 2.25 0.2 min, and 6 0.5 min. The decays of these activities have been investigated using a plastic scintillator, NaI(Tl) detectors, and a Ge(Li) detector. Beta and gamma ray spectroscopy verifies the existence of ⁶⁴CO, ⁶⁴CO, and ⁶¹Fe following the ⁶⁴Ni(n,d)⁶³Co, ⁶⁴N(n,p)⁶⁴Co, and ⁶⁴Ni(n,a)⁶¹Fe reactions, respectively. The decay schemes of ⁶³CO and ⁶¹Fe have been modified and a partial decay scheme of ⁶⁴Co has been proposed.
