Sensei Posted February 14, 2014 Share Posted February 14, 2014 (edited) Hello!On wiki pagehttp://en.wikipedia.org/wiki/Isotopes_of_carbonwe can read that decay energy of Carbon-11 isotope is11C -> 11B + e+ + Ve + 0.96 MeV The first one with 0.96 MeV is correct. I am receiving exactly the same value. 11C + e- -> 11B + Ve + 3.17 MeV But this one, I am not so sure whether it's correct. Can someone point me to other sources mentioning this decay energy of Carbon-11 to verify data.. ? The best would be couple independent sources. After posting I found this http://www.nucleide.org/DDEP_WG/Nuclides/C-11_tables.pdf which mentions 1.982 MeV as decay energy of Carbon-11 (decay through electron capture). And that was mine previously calculated value too (so I was quite surprised that it doesn't match wiki page).. Best Regards!

Enthalpy Posted February 14, 2014 Share Posted February 14, 2014 http://www.nndc.bnl.gov/sigma/index.jsp?as=11&lib=endfb7.1⊄=4 http://www.nndc.bnl.gov/sigma/getInterpreted.jsp?evalid=15920&mf=8&mt=457 1.982MeV decay energy, which is 2*0,511MeV more than 0.96MeV.

Sensei Posted February 22, 2014 Author Share Posted February 22, 2014 So it appears that wikipedia has incorrect data. Can someone with wikipedia account fix it? Change row: "11C + e- -> 11B + Ve + 3.17 MeV" to "11C + e- -> 11B + Ve + 1.982 MeV" Link to comment Share on other sites More sharing options...
