This table was introduced by an IP address in the first edit of the americium-141 page, https://en.wikipedia.org/w/index.php?title=Americium-241&diff=284520972&oldid=143366139

The validity or meaning was questioned on the talk page Talk:Americium-241. (Note: merging was done without placing notices or linking to the old talk pages, making it hard to trace edits.) Where does the beta decay come from?? I was looking for info on 241Am decay, but the Americium page seems to give better info. Ssscienccce (talk) 18:12, 13 July 2013 (UTC)

Hello fellow Wikipedians,

I have just added archive links to one external link on Isotopes of americium. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true or failed to let others know (documentation at {{Sourcecheck}}).

Am242m section

Whoever wrote this section does not have a good grasp of fission. All fissile materials can (and sometimes are) made into thin films as part of a fuel element. The key bit the author seems to be missing is that THIS example is based on an infinite reactor, not a single element, which is how other fuels and fuel elements are evaluated. This is also for the thermal (i.e. moderated) critical mass, which is different from the bare sphere mass. Comparing this critical mass with the generally given Pu239 figure is not appropriate.

Figure "Actinides and fission products by half-life"

This figure includes Ra-226 among the actinides which is not correct. It forms by actinide decay but is not an actinide. Will it form in significant amounts in spent fuel? It might be significant given the large amount of U-238 but given its half-life it will still be far from equilibrum.150.227.15.253 (talk) 14:18, 19 August 2021 (UTC)

The figure should have a footnote explaining that radium is added because of its relatively long half-life. 226Ra has a longer half-life than any Ac isotope and a comparable half-life to various isotopes of Th, Am, Cm, and Cf, and while the absolute quantity of 226Ra is still much less than 238U, it does exist in secular equilibrium in any U sample.

234Am: Spin 0−?

That looks impossible as 234Am as an odd-odd nuclide, but I'm not sure. 129.104.241.214 (talk) 17:01, 6 March 2024 (UTC)

Ah, I found that 16B, 22N, 16F, 50K, 90Rb, 92Rb, 96Y, 98Y, 116Ag, 134Sb, 144Pr, ... also have spin 0−. 129.104.241.214 (talk) 03:48, 10 March 2024 (UTC)
