经过将近三年的努力,以基奥尔沙(Ghiorso)为首的一些科学家在美国加州大学劳伦斯輻射实驗室合成并鉴定了一个新元素,它的原子序数是103,目前为周期表中最后面的一个元素,也是锕系元素中最后一个成员,关于这項工作的正式报告登载在“物理評論”,1961年5月份的一期上。发现者已经建议将这一元素命名为铹(Lawrencium),符号为Lw,以纪念迴旋加速器的发明人、諾员尔奖金获得者劳伦斯博士。利用能量为70兆电子比特的硼-10和硼-11的离子轰击鐦时产生一新的α放射性,α粒子能量为8.6
After nearly three years of hard work, some scientists, led by Ghiorso, synthesized and identified a new element at the Lawrence Radiation Laboratory at the University of California, U.S.A. It has an atomic number of 103 and is currently the last of the periodic table One element, also the last member of the actinide, a formal report on this work is contained in the May 1961 issue of Physical Review. The discoverer has suggested that this element be named Lawrencium, symbol Lw, in honor of the inventor of the cyclotron, Dr. Lawrence Bonn, a Novo Winner. A new alpha radioactivity was produced when bombarded with ions of boron-10 and boron-11 with energies of 70 mega-electron bits, with an alpha particle energy of 8.6
