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

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

thanks
