摘要：

Ampoules of amorphous 99.5% enriched 13 C were irradiated at the PF1b neutron beam line at the high-flux ILL research reactor in order to produce 14 C atoms. The precise ratio of 14 C/13 C was subsequently measured at the VERA Accelerator Mass Spectrometer, allowing the 13C(n,.)14C thermal cross section to be accurately determined. This is the first measurement of this cross section at sub-eV energies via this technique and the result of 1.52 +/- 0.07mb for the thermal cross section is in good agreement with other recent measurements which were performed via Prompt Gamma-ray Activation Analysis.
