In the half-life column of the table above, what are the figures in parentheses? Plantsurfer (talk) 17:48, 25 January 2013 (UTC)

Write in Plain English whenever possible[edit]

This article needed to be written in Plain English with minimal jargon in order to make it readable by the General Reader, and not just by physicists, chemists, nuclear engineers, and students thereof!98.81.7.165 (talk) 16:07, 20 November 2011 (UTC)

The Table[edit]

Thank you for the very useful table! —Preceding unsigned comment added by 128.120.106.4 (talk) 22:01, 9 May 2008 (UTC)

Spin of Nitrogen-14?[edit]

In the article (under the nitrogen-15 section) it is claimed that nitrogen-14 is spin-zero. I thought the only spinless nuclei were those with even proton and neutron numbers, whereas nitrogen-14 is odd-odd. Other places seem to claim that it's spin-one, which makes more sense. If nitrogen-15 is the predominant isotope used for NMR, it's probaby because spin-half nuclei have simpler splitting patterns, which are easier to analyse. — Preceding unsigned comment added by 131.111.185.74 (talk) 18:01, 2 February 2012 (UTC)

stable-isotope probing[edit]

Why does stable-isotope probing redirect here? SIP is not limited to N-15, it is commonly conducted with isotopes of H, C, O, and P as well. Shouldn't SIP have its own page? Civiello m (talk) 08:08, 26 February 2014 (UTC)
