Add new entries in C-14 for Tellurium 131 and Neodymium 137 #65
Comments
looks good to me so I support this proposal |
@amilan17 create branch |
@SibylleK branch is ready for editing |
@amilan17 : could you let Joerg from TT-WIGOSMD know that we are adding new entries in Common Code Table 14 because we may want to synchronise table 1-01-01 in WMDS repository. I tried to tag him but I don't think it works as he is not part of our team. Thanks |
@amilan17, branch is updated |
Not much information is available through online search about Nd-137. It seems this isotope does not exist in the natural environment: In 1970 137Nd was reported in “135mCe and 137mNd: Isomeric States in N = 77 Isotones” by Droste et al. [20]. https://people.nscl.msu.edu/~thoennes/2009/neodymium-adndt.pdf |
Dear @gaochen-larc, Links: |
@SibylleK Thank you very much for the information! I totally can see Nd-137 can be useful to verify the atmospheric dispersion models since it does exist in the natural environment. I think we leave the CAS and PubChem numbers blank. Possibly add a comment to indicate this is a manmade isotope. Comments? Maybe we can close this issue now. |
@SibylleK I think this is ready, unless you want to add a note? |
