Elements 115 and 113 discovered in Dubna

A team of Russian and American physicists that discovered elements 114 and 116 in 1998 and 2000 now believe they may have created two other superheavy elements – 113 and 115.
If confirmed, these results would lend even more weight to the idea of an “island of stability” at the edge of the periodic table (Y Oganessian et al. 2003 Phys. Rev. C 69 021601)
Yuri Oganessian and colleagues at the Joint Institute for Nuclear Research in Dubna, Russia - collaborating with a team from the Lawrence Livermore National Laboratory in the US - have collided calcium-48 with americium-243 nuclei to produce element 115.
