The principle of two kinds of primary coincidence technique in the present work. (a) Fission fragments-γ1-γ2-γ3 coincidence method: An isomer is implanted into solar cells, followed by isomeric decay with triple or more γ rays. (b) β-γ1-γ2-γ3 coincidence method: A β decay is measured by fast plastic scintillators, followed by a cascade γ ray transition. The feeder (γ2) and decay (γ3) of excited state of interest represented by τ (orange) are detected by LaBr3(Ce), while the precursor transition (γ1) is measured by HPGe.
