Talk:Isotopes of oxygen

Heaviest isotope

According to http://www.sciencedaily.com/releases/2007/09/070913170108.htm , the heaviest possible oxygen isotope is O-24. Since this is more up-to-date than the given references here, I think we should delete all higher isotopes from the table. --Roentgenium111 (talk) 16:53, 9 June 2009 (UTC)

Done. --Roentgenium111 (talk) 14:19, 5 July 2009 (UTC)

Heavier oxygen isotopes exist but for too brief a time to undergo beta decay. O-25, O-26, O-27 and O-28 have been discovered see Nubase 2003 at the AMDC website or Nuc. Phys. A 729, 3 (2003) for the discovery references. Darian2 (talk) 05:14, 31 August 2012 (UTC)

Shortened footnote format

I converted the shortened footnotes in this article to a much simpler format using {{sfn}}. If you object to this in any way and want me to revert them, I'd be happy to do so. Just contact me on my talk page.

The old version made an unnecessary call to {{wikicite}} and was more complicated to read in edit-mode. ---- CharlesGillingham (talk) 18:08, 29 September 2010 (UTC)

Factual error

There's a nonsense statement in the first paragraph. It is written there that "The shortest-lived is 12O with a half-life of 0.4 MeV.". Time cannot be measured using this unit I'm afraid. Please fix it. Regards, 83.6.45.47 (talk) 22:06, 23 November 2011 (UTC)

Oxygen 13

"Oxygen-13 is an unstable isotope of oxygen to provide any nutrients outside of the zone." What does this mean? Klausok (talk) 11:27, 22 January 2012 (UTC)

Number of isotopes

Is there a reason that isotopes O-25 through O-28 are not included in the table? The following statement is confusing: "17 radioactive isotopes have also been characterized, with mass numbers from 12O to 24O, all short-lived, with the longest-lived being 15O with a half-life of 122.24 seconds." The seventeen isotopes refers to O-12 through O-28, but the table only references O-12 through O-24. I shouldn't have to go to the talk pages to find why there is a discrepancy.

CNO cycle

This article doesn’t mention ¹⁵
O
's role in the CNO cycle. –LaundryPizza03 (dc̄) 19:05, 8 May 2018 (UTC)

^25-28O

If ²⁵O to ²⁸O have been observed, then why aren’t they on the list? Being beyond the neutron drip line, as far as I know, is not a good reason. –LaundryPizza03 (dc̄) 02:03, 9 May 2018 (UTC)

Oxygen-11

Apparently discovered a few weeks ago: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.122.122501 Reyk _YO! 17:54, 18 April 2019 (UTC)

Is there data for oxygen 11 yet

If yes add data right now and Merry Christmas 24.115.255.37 (talk) 17:44, 26 December 2021 (UTC)

Thank you; it turns out there is data in {{NUBASE2020}}. I updated the table accordingly. ComplexRational (talk) 22:49, 26 December 2021 (UTC)

Oxygen-15 natural occurrence

Shouldn't oxygen-15 be listed as "trace" rather than "synthetic " , since traces are produced by lightning. 2603:6000:8740:54B1:5C62:6332:F746:B663 (talk) 02:16, 14 June 2023 (UTC)

Can you provide the relevant source that show the existence of ¹⁵O isotope during the storm? I found that rather than produced by lightning, this isotope occurs briefly in the cold nucleo-synthesis cycle in various stars, much similar to the way ⁸Be isotope present in triple alpha process of stars (see CNO-I) 2402:800:63AC:B4A6:A93C:AC98:8D6E:845C (talk) 06:04, 23 June 2023 (UTC)

See ) Lightning leaves behind a radioactive cloud ) and ( wikipedia/ isotopes of nitrogen) with the nitrogen-13 section. Also, scroll down to oxygen-15 on this page. 2603:6000:8740:54B1:FC27:25E0:460:FB3C (talk) 20:26, 10 July 2023 (UTC)

Oxygen-28

Here is an article from Science News: Scientists finally detected oxygen-28. Its instability surprised them. Rjluna2 (talk) 16:12, 29 October 2023 (UTC)
