WebCarbon-11. Carbon-11 or 11 C is a radioactive isotope of carbon that decays to boron-11.This decay mainly occurs due to positron emission, with around 0.19–0.23% of decays instead occurring by electron capture. It has a half-life of 20.3402(53) min.. 11 C → 11 B + e + ν e + 0.96 MeV 11 C + e − → 11 B + ν e + 1.98 MeV. It is produced from nitrogen in a … WebMay 1, 2002 · And R is calculated from the δ 13 C ratios as measured with the IRMS equipment using the reverse of Eq. 1. Another effect of measuring isotope ratios rather than absolute amounts is that detectable amounts of label also depend on pool sizes or concentrations of the components to be analysed. ...
