PRODUCTION OF Lu178 BY THE Ta181(n, α)Lu178 REACTION IN THE NRX REACTOR

摘要: A rare earth activity of half-life 19 ± 1 min, produced by irradiating tantalum in the fast neutron flux NRX reactor has been shown to be a lutetium nuclide. The 19 ± 1 min was ascribed Lu178 Ta181 (n, α)Lu178 reaction. Three γ rays 450 ± 15 kev, 320 ± 15 kev, and 680 ± 15 kev (very weak) are associated with activity.
