Abstract
By bombarding the natural thorium targets with 14 MeV neutrons, 229Ra was produced through the reaction 232Th(n,α)229Ra. The radium activities were separated from the irradiated targets by coprecipitation with the BaCl2. A total of 18 new weak γ rays with energies of 14.5, 15.6, 18.8, 21.8, 22.5, 44.0, 47.5, 55.0, 63.0, 69.6, 93.6, 94.1, 98.5, 102.2, 104.5, 106.1, 161.1, and 171.5 keV which could be assigned to the decay of 229Ra were observed in the isolated radium fractions employing high resolution HPGe detectors and γ(χ)- γ coincidence methods. A decay scheme of 229Ra based on these observations is proposed.
