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, because multiple kids played with themselves and the remains is collected here. References are denoted by these letters:

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.

• (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.
