摘要：

A new isotope (265)Bh was produced and identified at the Sector Focus Cyclotron of the Heavy Ion Research Facility in Lanzhou. This experiment was performed via the reaction of an Am-243 target with 168 MeV Mg-26 ions. Identification was made by observation of correlated alpha-particle decays between the new isotope (265)Bh and its (261)Db and Lr-257 daughter nuclei rising a set of rotating-wheels system. A total of 8 correlated decay events of (265)Bh and 4 decay events Of (264)Bh were observed. (265)Bh decays with a 0.94(-0.31)(+0.70) s half-life by emission of a-particles with an average energy of 9.24 +/- 0.05 MeV. The half-life and a decay energy of (265)Bh from this experiment are in agreement with theoretical predictions.
