摘要
用39 MeV-α粒子轰击天然钨靶产生了^(183)Os测量了^(183)Os衰变的γ-β符合谱,确定了β^+能谱的端点能量。最终提取出^(183)Os衰变的Q_(EC)值:Q_(EC)=2.24±0.10 MeV,与系统学的估计值:2.304±0.10MeV在误差范围内相符。
Activities of ^(183)Os were produced by 39 MeV a particles bombarding on a natural tungsten target. β^+ spectrum with coincidence gate set on the strongest 382 keV γ-rays of ^(183)Os decay was measured. The endpoint energy of the β^+ spectrum was determined and the Q_(EC) value of^(183)Os decay was extracted to be 2.24±0.10 MeV which is in good agreement with the predicted value 2.30±0.10 MeV on the basis of mass systematics.
