Abstract:
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.
