When livermorio atoms were first produced in 2000, they were obtained during a fraction of a second (47 milliseconds). The first successful attempt to create atoms of this element was made at the Joint Institute for Nuclear Research (JINR), Dubná, Russia. The team worked with material provided by Lawrence Livermore National Laboratory in California, USA. This highly radioactive element was produced by colliding atoms of calcium, 48Ca, with atoms of curium, 248Cm, in a particle accelerator.
