在RIKEN Nishina中心的BigRIPS分离器的实验中，我们观察到两个质子（）发射。与此同时，没有证据表明这种外来放射性的另外两个潜在候选者，可以观察到。这一观察结果与价值预测相一致，该预测指出，作为最好的新候选者，在三个双质子radioactivity.is只有第四个基态发射体被观察到，其半衰期为几毫秒.衰变能量为1690（17）keV，发射分支比为37（14）%，半衰期为7.4（30）ms。
In an experiment with the BigRIPS separator at the RIKEN Nishina Center, we observed two-proton () emission from. At the same time, no evidence foremission ofand, two other potential candidates for this exotic radioactivity, could be observed. This observation is in line withvalue predictions which pointed toas being the best new candidate among the three for two-proton radioactivity.is only the fourthground-state emitter to be observed with a half-life of the order of a few milliseconds. The decay energy was determined to be 1690(17) keV, theemission branching ratio is 37(14)%, and the half-life ofis 7.4(30) ms.
