Data 2003
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.

 * See Isotopes of copper. It means that the number is a guess. — Preceding unsigned comment added by 92.27.109.117 (talk) 11:42, 19 February 2013 (UTC)


 * No one should belabor a colleague (and especially not a presumably generous ip-address colleague), for failing to add more than that cryptic pointer. (And if I fail to remedy the unmet need, as I well may, all colleagues are justified if they choose to groan back (articulately or or otherwise) abt admins failing to qualify as the answer to a maiden's (or anyone else's) prayer.
