Data 2003

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.

  • (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.

Lose the column "decay energy"

Where's the column "decay energy"? — Preceding unsigned comment added by 59.126.202.81 (talk) 16:42, 22 July 2012 (UTC)
