Table of Nuclides
Frequently Asked Questions
|2.1: Decay Data|
|I found a major discrepancy between the your library (presumably the NUDAT database) and other sources. Your library reports the following half-lifes:
Rh102 = 207 day, Rh102m =2.9 years.
Whereas the Joint Evaluated File (JEF) library, the Erdtmann and Soyka database, and the "The Chart of the Nuclides" report:
Rh102 = 2.9 year, Rh102m = 207 day.
Do you have any information concerning this discrepancy?
|The Table of Nuclides is based on the NUDAT (by NNDC/BNL). NUDAT is based on ENSDF (Evaluated Nuclear Structure and Decay File). So the US origin or Japanese data files use the value recommended by ENSDF.
However, I have found that The Karlsruher Nukidekarte (1981) says that:
The assignment of decay properties to the metastable or ground state is uncertain.
I do not have recent KfK chart.
However, Chart of Nuclides by General Electric, Japanese Nuclear Data commitee
has same value as NUDAT.
