Introduction

This article is part of Wikipedia:Wikiproject Isotopes. Please keep style and phrasings consistent across the set of pages. For later reference and improved reliability, data from all considered multiple sources is collected here. References are denoted by these letters:

  • (A) G. Audi, O. Bersillon, J. Blachot, A.H. Wapstra. The Nubase2003 evaluation of nuclear and decay properties, Nuc. Phys. A 729, pp. 3-128 (2003). — Where this source indicates a speculative value, the # mark is also applied to values with weak assignment arguments from other sources, if grouped together. An asterisk after the A means that a comment of some importance may be available in the original.
  • (B) National Nuclear Data Center, Brookhaven National Laboratory, information extracted from the NuDat 2.1 database. (Retrieved Sept. 2005, from the code of the popup boxes).
  • (C) David R. Lide (ed.), Norman E. Holden in CRC Handbook of Chemistry and Physics, 85th Edition, online version. CRC Press. Boca Raton, Florida (2005). Section 11, Table of the Isotopes. — The CRC uses rounded numbers with implied uncertainties, where this concurs with the range of another source it is treated as exactly equal in this comparison.
  • (D) More specific level data from reference B's Levels and Gammas database.
  • (E) Same as B but excitation energy replaced with that from D.

Main Isotopes: 166m1

I edited the introduction to change 166m to 166m1. This isotope should also appear in the main isotopes table due to its long half life. — Preceding unsigned comment added by 91.110.14.206 (talk) 20:43, 24 December 2020 (UTC)

Large Break

I notice a large break from the heading "List of isotopes" and the table, probably due to the holmium isotopes template on the right, which could be a bit too wide. This break seems unnatural to the article, so is there any way to fix this? --Ammonium121 (talk) 23:07, 1 February 2021 (UTC)

It might be a display issue on your device if you have a small screen; if the zoom is high enough or the screen width is less than the combined width of the isotopes table and isobox, there is a gap. I don't have it at my normal zoom, and there's nothing else in the wikitext causing it, so the only way to fix it would be zooming out or using a different device.
