Talk[edit]

This is really awkward working: "the primary decay mode after stable is x and before stable is y". Pretty sure that's referring to before and after in order of Z. Can we clarify this please? 128.171.31.194 (talk) 22:23, 30 August 2010 (UTC)

Manganese 60[edit]

The isotope OO25Mn60 Has a halflife of 50 seconds and the adjacent isotope OE25Mn59 has a much lower halflife of 4.6 seconds and OEMN2561 a much lower halflife of 1.67 seconds which is an irregularity, due to the OO60 isotope's being more stable than the adjacent OE isotope on either side. Also, the halflife of OE25Mn57 looks low at 85 seconds compared to OO25Mn56 @ 2.6 hours and OO25Mn58 @ 65 seconds. WFPM (talk) 22:38, 27 November 2011 (UTC)
