F-18 decay modes in the big List
editThe infobox in top (and the element main infobox) says F-18 decays by β+ and by electron capture (ε). However, the #List_of_isotopes on this page does not mention that 2nd decay mode. I'd expect the list to be ultimately complete. Is the list incomplete, or is my understanding incomplete? (and, my original quest shortcut: does that ε decay mode have its own spin value? Or is the spin value for the isotope once?) -DePiep (talk) 16:02, 8 June 2017 (UTC)
- @DePiep: (apparently I missed this question): Whenever beta-plus decay is possible, electron capture is also possible, so it is not normally listed separately in sources. Spin values are for each isotope/isomer. Double sharp (talk) 03:24, 3 June 2019 (UTC)
Fluorine-13?
editIs there data yet 24.115.255.37 (talk) 17:47, 26 December 2021 (UTC)
- Unfortunately, there's no more recent data that I'm aware of; the half-life is still unknown. ComplexRational (talk) 23:09, 26 December 2021 (UTC)
- Do we consider https://www-nds.iaea.org/relnsd/vcharthtml/VChartHTML.html to be reliable? That lists Fluorine 13 with a half-life of 450*10^-24 seconds, or 450 yoctoseconds, which would make it the most unstable fluorine isotope by about 50 yoctoseconds. InkTide (talk) 17:58, 8 April 2023 (UTC)
- A decay width of 1.01(27) MeV [t1/2 = 0.45+0.16
−0.10 zs] is measured for the observed 5/2+ state; a 1/2+ state is predicted as well, but has not been observed. Should I list this in the table with the 5/2+ state only? –LaundryPizza03 (dc̄) 00:56, 2 September 2024 (UTC)
Fluorine-18 trace?
editHow could there be trace 18F? 103.166.228.86 (talk) 09:50, 7 September 2024 (UTC)
- From cosmic rays: 18O(p,n)18F produces it, as well as spallation of atmospheric Ar. Double sharp (talk) 11:24, 7 September 2024 (UTC)
- OK thanks! 103.166.228.86 (talk) 15:28, 9 September 2024 (UTC)
