[edit]on a the page http://ie.lbl.gov/toi/nuclide.asp?iZA=550137, in the tables of decays at the bottom (eg the gamma from 137Cs table) the % is quoted. This looks a bit like a branching ratio. Is it? what does the I stand for? (the g is presumably gamma)--87.127.117.246 12:26, 13 January 2007 (UTC)
I think it might be intensity --87.127.117.246 12:39, 13 January 2007 (UTC)
Calculation errors?
[edit]I was looking at this page to figure out partial half lives, and I believe I encountered several calculation errors in the current page. However, I am not an expert in this area so I am not sure if the following is correct. First off, based on the half life, we can calculate the decay constant:
The decay rates of the individual processes are equal to multiplied by their individual percentages, i.e.:
- <-- different!
and
According to the page on exponential decay, the total decay constant of two independent events is equal to the sum of the individual decay constants. This appears to agree with my results above. Correspondingly, the partial half lives should therefore be:
and
- <-- different! — Preceding unsigned comment added by Bluskale (talk • contribs) 17:15, 26 August 2015 (UTC)
