| 英文摘要 | An Isotope of element 105 with mass number 259 has been produced via the reaction Am-241(Ne-22,4n) (259)Db at E-lab = 120MeV. The reaction products were transported and collected using the helium-jet technique and rotating wheel apparatus. The alpha -decays of the products and their daughter nuclides were detected by a series of Si(Au) detectors. The Z and A of the nuclide have been unambiguously identified by the genetic relationship between the new activity and the known nuclide Lr-255. The new nuclide (259)Db has a half-life of (0.51 +/- 0.16)s and decay by alpha-particle emission with energy of 9.47MeV. The Q(a) value for new isotope (259)Db is in good coincidence with the predicted result. |
