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