New isotope doubles up

An international team of nuclear physicists has created zinc-54 for the first time. Moreover, they have confirmed that it can undergo two-proton decay, a rare process that has only been seen in one other isotope before (nucl-ex/0505016). The results should shed more light on how protons are bound together in the nucleus. Nuclei decay when they contain too many neutrons or too many protons to be stable. The most commons forms of decay are nuclear fission and alpha, beta and gamma decay.
