Talk:Calcium-48

From Wikipedia, the free encyclopedia

[edit] Half-life inconsistency

The calcium-48 article mentions a half-life of 4.3 × 10¹⁹ years. Because no uncertainty is specified, that would implicitly mean (4.3 ± 0.1) × 10¹⁹ years. The cited source (Balysh et al.) gives a much larger uncertainty of (4.3 (+2.4 −1.1 stat.) (± 1.4 syst.)) × 10¹⁹ years. It would appear that the source has been grossly misquoted.

The article on isotopes of calcium gives a half-life of (5.3 ± 1.7) × 10¹⁶ years.

In short, this is a mess. I'll correct as soon as I can find a reliable source.

I don't think that there is a more reliable source than the original paper, of which you can find a preprint here. Icek 17:42, 12 November 2007 (UTC)
