Think zinc!

An international team of researchers has produced a new isotope of zinc, zinc-54, which they say undergoes the rare process of two-proton decay. The research carried out by Bertram Blank of the CENBG laboratory in France and colleagues could shed light on what how protons stay together in the atomic nucleus. Carrying out nuclear physics experiments with this new isotope is relatively straightforward but don't expect to see it bottled for off-the-shelf chemistry. The manufacturing process is very low yield with only one in 10 to the 17 collisions between nickel-58 atoms and a nickel target yielding the novel zinc-54 species.
