To study the decay scheme of (126)Sn, two samples of a purified solution were measured by gamma-ray spectrometry and the relative photon emission intensities were determined. The (126)Sb(m) isomeric branching ratio was derived to be 18.6 (6) %. The maximum beta energy of the (126)Sn decay was checked by liquid scintillation. The Kbeta/Kalpha intensity ratio of Sb was determined being 0.226 (11). These new experimental results were used to re-examine the whole decay scheme of (126)Sn and its daughters.
为研究¹²⁶Sn的衰变纲图，用γ射线能谱法对两份纯化溶液样品进行了测量，并测定了相对光子发射强度。推导出¹²⁶Sb(m)的同质异能分支比为18.6(6)%。通过液体闪烁法检验了¹²⁶Sn衰变的最大β能量。测定了Sb的Kβ/Kα强度比为0.226(11)。利用这些新的实验结果重新审视了¹²⁶Sn及其子体的整个衰变纲图。
