12, 2012, after colliding zinc nuclei together in a thin layer of bismuth.

Nihonium has six isotopes with known half-lives.
How was 113 discovered?
The search at RIKEN for element 113 started in September 2003, when Morita's group began bombarding a thin layer of bismuth with zinc ions travelling at about 10% the speed of light. Theoretically, they would occasionally fuse, forming an atom of element 113.
