Abstract: An Isotope of element 105 with mass number 259 has been produced via the reaction 241Am(22Ne,4n)259Db at Elab=120MeV. The reaction products were transported and collected using the helium-jet technique and rotating wheel apparatus. The α 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 255Lr. The new nuclide 259Db has a half life of (0.51±0.16)s and decay by alpha particle emission with energy of 9.47MeV. The Qα value for new isotope 259Db is in good coincidence with the predicted result.
