Half-life of OO45Rh 104

edit

After the OO45Rh 102 reaches it isotope with the maximum OO45Rh isotope stability halflife value (29 years, Logsecond=7.96), the OE45Rh 103 isotope is the only stable 45Rh isotope. Then the next isotope OO45Rh 104 is reported to drop in halflife value to only 4.36min (logsecond=2.42). Then the next OO45Rh 106 isotope recovers to a halflife of 2.18 hours (logsecond=3.89). This low value of the isotope OO45Rh 104 is an irregularity in the stability halflife profile of the OO45Rh Rhodium isotopes.WFPM (talk) 20:34, 27 September 2011 (UTC)Reply

Negative isomer excitation energy?

edit

For Rhodium-110m (and possibly Rhodium-108m, but that one has wider uncertainty), the excitation energy is listed as negative. Shouldn't the base state always be the one with the lowest energy? — Preceding unsigned comment added by 65.183.206.186 (talk) 17:05, 20 September 2017 (UTC)Reply
