利用充气反冲光谱仪（SHANS）和数字数据采集系统，研究了Pa衰变的精细结构。通过重离子诱导的Ar+ w聚变蒸发反应，在1p3n蒸发通道中产生核素。基于ER-和相关测量，除了之前已知的三个分支外，还观察到三个新的衰变。将衰变能量最大的一个视为基态到基态的跃迁。新测得的Pa的衰减特性在减小宽度的框架中进行了检验。
With the help of the gas-filled recoil spectrometer SHANS and a digital data acquisition system, the fine structure of the decay for Pa was studied. The nuclides were produced through the 1p3n evaporation channel via the heavy-ion induced fusion evaporation reaction Ar+ W. Based on the ER--- and-correlation measurement, three new decays were observed in addition to the three branches known previously. The one with the largest decay energy was regarded as the ground state to ground state transition. The newly measured decay properties of Pa were examined in a framework of reduced width.
