词汇 lawrencium
词源
lawrencium. While a physics professor at the University of California in 1930, Ernest Orlando Lawrence invented and built the first atom-smashing cyclotron, for which he was awarded the Nobel Prize nine years later. The physicist also played a prominent role in the development of the atomic bomb while director of the radiation laboratory at Berkeley, California, conducting research into the separation of U-235. Lawrence died in 1958, aged 57. In 1961 Albert Ghiorso, Almon Lash, and Robert Latimer created a new synthetic radioactive element at the laboratory dedicated to its former director. Law- rencium, its atomic number 103, is believed to be a “dinosaur element” that first formed when the world was born and de- cayed out of existence within a few weeks.
