Talk:Isotopes of xenon

Why is Xenon-108 not on the table?[edit]

Why does the table begin at ¹¹⁰Xe instead of ¹⁰⁸Xe? — Preceding unsigned comment added by Balgontork (talk • contribs) 13:37, 20 May 2013 (UTC)[reply]

Here's a reference for ¹⁰⁸Xe: https://link.springer.com/chapter/10.1007/978-3-540-69945-3_3397. A ¹⁰⁹Xe is also listed at NNDC's database. –LaundryPizza03 (d c̄) 23:57, 31 May 2018 (UTC)[reply]

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Isotopes of xenon. 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:

Added archive https://web.archive.org/20070927183750/http://www.shef.ac.uk/physics/bus2006/talks/luscher_roland.pdf to http://www.shef.ac.uk/physics/bus2006/talks/luscher_roland.pdf

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Xenon 124 decay[edit]

The article says that Xenon 124 is stable, but [this report] says that they just saw one decay. Bubba73 ^{You talkin' to me?} 19:33, 24 April 2019 (UTC)[reply]

It is one of isotopes subject to Double beta decay. Ruslik_Zero 20:23, 24 April 2019 (UTC)[reply]

The article does not actually say that it is stable. It says that it is "observationally stable" with a note. Ruslik_Zero 20:27, 24 April 2019 (UTC)[reply]

@Bubba73 and Ruslik0: That new article is correct; the decay of ¹²⁴Xe was indeed observed for the first time and is documented in ^[1] (abstract only for now). I updated the isotopes list, templates, and article with this information. Thank you for pointing this out, Bubba73. ComplexRational (talk) 23:00, 24 April 2019 (UTC)[reply]

@ComplexRational: We should probably also update the tables in Primordial nuclide and List of nuclides to include ¹²⁴Xe as unstable, too. (I have made a start on the former, along with some other articles which counted the number of stable nuclides.) Double sharp (talk) 05:22, 25 April 2019 (UTC)[reply]

Cristiano Toàn (talk) 12:01, 13 February 2024 (UTC) ¹³⁴Xe is engergically allowed to undergo double beta decay. However it decay energy is relative low 0.825 MeV. By comparison ¹³⁶Xe's double beta decay has energy 2.462 MeV and have life 2.38x10^21 years[reply]
