Decay scheme study of 126Sn and 126Sb

To study the decay scheme of 126Sn, two samples of a purified solution were measured by gamma-ray spectrometry and the relative photon emission intensities were determined. The 126Sbm isomeric branching ratio was derived to be 18.6 (6) %. The maximum beta energy of the 126Sn decay was checked by liquid scintillation. The Kβ/Kα intensity ratio of Sb was determined being 0.226 (11). These new experimental results were used to re-examine the whole decay scheme of 126Sn and its daughters.
