2005 data
This article is part of 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 729, pp. 3-128 (2003). &mdash; 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.

This page says that Neodymium-145 is stable, but both Isotope table (divided) and Isotope table (complete) say that that isotope is radioactive. —The preceding unsigned comment was added by 202.89.32.154 (talk • contribs).


 * Fixed those, as per the references here. Thanks for pointing it out. Femto 14:02, 5 April 2007 (UTC)
