| 1 | Production and Identification of New Isotope ^(265)Bh(Z=107)显示文摘New Isotope ^265Bh was produced in bombardment of a ^243Am target with 168 MeV 26Mg ions. The experiment was carried out at the Sector Focus Cyclotron of Heavy Ion Research Facility in Lanzhou in 2003. The reaction products were transported and collected by using helium-jet technique and a set of rotating wheel system. Identification was made by observation of correlated a-particles between the new isotope ^265Bh and its ^261Db and ^257Lr daughter nuclei. A parent-daughter searching mode was used to facilitate detection of α-α correlations. A total of four pairs of PIPS detector (200mm^2 active area) were used to measure the kinetic energy of a particles. The a particle energy resolution was about 40 keV for the top detectors and 100 keV for the bottom detectors because of energy degradation in the polypropylene foil. | FanHongmei WuXiaolei GanZaiguo GuoJunsheng QinZhi LeiXiangguo LiuHongye GuoBin XuHuageng ChenRuofu DongChengfu ZhangFuming WangHualei XieChengying FengZhaoqing ZhenYong SongLitao LuoPeng XuHushan ZhouXiaohong JinGenmin RenZhongzhou | 2003 | 近代物理研究所和兰州重离子加速器实验室年报:英文版2003，，1： | 0 |
