i am looking at the decay scheme of Sn126 > Sb 126 > Te126 and would like to know how many gamma rays Sb126 throws out on average and see if i've understood the diagram correctly;- Sn128 -> decays to (126m-Sb) 19.5min half life, where 14% decays through IT with 17.7 kev gamma and then 12.46 day half life 126 Sb. The other 86% of the isomer has 414.5kev, 666.1kev and 694.8kev gamma and various 1mev beta, according to (page 4). So only 14% goes through the 12 day decay scheme while the rest goes though a 19.5min decay scheme. What also confuses me is that is says 100% beta decay in the diagrams while there are tables for gamma emissions, is this for red numbers in the diagrams, occasional gamma emissions? eg p5(adsbygoogle = window.adsbygoogle || []).push({});

Also what is the average energy of beta given of and has anyone seen a more complex decay scheme?

thanks
