Properties and data of the isotope 11 C. Carbon-11 or 11 C is a radioactive isotope of mass 11 of the element carbon, which has a half-life of about 20, 5 minutes decays to boron-11. The atomic nucleus of the nuclide is made up of 5 neutrons and the 6 element-specific protons.
Carbon (6 C) has 14 known isotopes, from 8 C to 20 C as well as 22 C, of which 12 C and 13 C are stable. The longest-lived radioisotope is 14 C, with a half-life of 5.70(3) × 10 3 years. This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reaction 14 N + n → 14 C + 1 H. The most ...
3 kwi 2019 · This can easily be understood by considering that the ratio between the total mass of a 11 C-labeled precursor (carbon-12 and carbon-11) and the precursor for labeling typically is in the order of 1/100.
