Nuclear data sheets for A=234

The evaluators present in this publication spectroscopic data and level schemes from radioactive decay and nuclear reactions for all isobars with mass number A=234. This evaluation includes the discovery of two activities: Cm-234., and Bk-234, which decay with half-lives of 51 s (2002CaZZ) and approximate to 140 s (2003MoZX,2003MoZT), respectively.
