| 英文摘要 | A new nuclide Th-238 has been produced via multinucleon transfer reaction induced by 60MeV/u O-18 ion irradiation of natural uranium. The thorium was radiochemically separated from the mixture of uranium and its reaction products. The activity of thorium was measured by using a HPGe detector and a planar HPGe detector. The Th-238 has been identified for the first time by measuring the growth and decay of the gamma-rays from its daughter Pa-238. The half-life of Th-238 was determined to be (9.4 +/- 2.0)min. In addition, a new (89.0 +/- 0.3)keV gamma-ray with T-1/2 = (8.9 +/- 1.5)min was observed and assigned to Th-238 decay based on the measurement of transition energy and half life. |
