我国核物理基础研究又取得重要成果,中国科学院近代物理研究所的科研人员利用兰州重离于加速器提供的丰中子束流氧-18轰击天然铀靶,使用奇异多核子转移反应,在可裂变核区成功地合成并研究了重丰中子新核素镤-239,日前,有关论文已被世界一流的德国物理杂志接受,既将发表。 新核素的合成和研究是当今核物理学科的重大基础性前沿领域之一,具有重要意义和很大的技术难度,为世界上各核物理中心所瞩目。中科院近代物理所经过几年的艰苦努力,已在重质量丰中子区合成和鉴别了质量数为185、208和237的铪、汞和钍的新核素,将该项研究推进到更为困难的“可裂变核区”。镤-239的成功合成是近物所在该质量区取得的更为引人瞩目的进展之一,是他们在重质量丰中于区独具特色的物理思想和技术路线的进一步发展。
Researchers at the Institute of Modern Physics, Chinese Academy of Sciences, use natural abundance of nuclear uranium targets to bombard natural uranium targets with rich neutron beam oxygen-18 provided by Lanzhou Heavy Ion Accelerator. Using fissile The nuclear zone has successfully synthesized and studied the heavy new neutron neutron 镤 -239, a few days ago, the papers have been accepted by the world-class German physical magazine, will be published. The synthesis and research of new nuclides is one of the major basic frontier fields of nuclear physics nowadays. It is of great significance and great technical difficulty, attracting the attention of all the nuclear physics centers in the world. After several years of painstaking efforts in modern physics of the Chinese Academy of Sciences, new nuclides of hafnium, mercury and thorium with mass numbers of 185, 208 and 237 have been synthesized and identified in the heavy-mass Fengzijie area and the study has been further promoted Difficult “fissile core zone.” The successful synthesis of 镤-239 is one of the more remarkable progress made by the near object in this quality area, which is their further development of the unique physical thinking and technical route in the area with high quality.
