The \(\beta \) decay endpoint energies corresponding to the decay from \(^{150}\)Pm to levels in \(^{150}\)Sm have been measured for the first time. The measurement has been made with a \(\beta -\gamma \) coincidence setup of two thin window Planar HPGe detectors and four Clover HPGe detectors. This measurement is a part of the program, taken up at VECC, on \(\beta -\gamma \) spectroscopy that would be utilized to characterise long lived \(\beta \) decaying isomers in nuclei.

$$ \ beta $$β-$$$ {150} $$ 150 Pm的衰减终点能量测量$$ \ rightarrow ^ {150} $$→150 Sm，使用$$ \ beta-\ gamma $$β-γ重合

首次测量了与从\（^ {150} \） Pm到\（^ {150} \） Sm中的电平的衰减相对应的\（\ beta \）衰减端点能量。测量已经由具有一个\（\β - \伽马\）两个薄的窗口平面HPGe探测器和四个三叶草HPGe探测器的重合设置。该测量是VECC中\（\ beta-\ gamma \）光谱研究程序的一部分，该光谱将用于表征原子核中长寿命\（\ beta \）衰变异构体。
