What theory?
It was: "151Eu was recently found to be unstable to alpha decay with half-life of yr, in reasonable agreement with theoretical predictions." I have taken the latter part out, because it doesn't say what theory is meant. —Preceding unsigned comment added by Phr en (talk • contribs) 09:02, 29 February 2008 (UTC)
Low Half-life values of OO63Eu144 and OO63Eu140
The reported half-lives do not agree with the half-life trend line of the rest of the 63Eu Europium OO type isotopes.WFPM (talk) 23:42, 21 April 2013 (UTC)
How would 153
Eu decay to a much less stable isotope, 149
Pm?
Because 149
Pm is way too unstable, so shouldn't 153
Eu be stable too? 80.98.179.160 (talk) 07:06, 26 March 2018 (UTC)
