Half-life of Rh-102m[edit]

I notice that different sources in the table given show two different values. I changed it in the article before seeing this. I will try to research it in the library & get it right (other web sites have the 2.9 year figure, but they may be recycling the same information; however, Berkeley Labs at http://ie.lbl.gov/education/parent/Rh_iso.htm also shows the 2.9 year figure Markjoseph125 07:12, 27 January 2007 (UTC)

Reference, as per the Nubase2003 evaluation, is doi:10.1016/S0969-8043(98)00057-8 which seems the most recent and reliable. Far as I see, http://ie.lbl.gov/databases/data/102/102RH/ens102RH.html is much older. Femto 16:01, 27 January 2007 (UTC)

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)
