三重衰变链首次被直接观测到。将原子核注入到双面硅条探测器中，可以使它们的衰变与子核和孙核的衰变在位置和时间上相关联。总共有17个事件被分配到三重衰变链。测得的衰变能量为20 keV，比以前测得的值高70 keV，并提高了半衰期的测量精度。给出了19035（45）keV的修正值。
The triple-decay chainhas been directly observed for the first time, following thereaction. Implantation ofnuclei into a double-sided silicon-strip detector has allowed theirdecays to be correlated in position and time with thedecays of the daughterand granddaughternuclei. In total, 17 events have been assigned to thetriple-decay chain. The energy of thedecay has been measured to be(20) keV, which is 70 keV higher than the previously measured value, and the half-life ofhas been measured with improved accuracy, to bems. A revisedvalue of 19 035(45) keV foris presented.
