Measurement of the 13C(n,γ) 14C cross section at stellar energies

The 13C(n,γ) 14C reaction cross section at stellar energy is crucial in studying the roles of the reaction in nucleosynthesis both in the early universe and in stellar helium burning. A new measurement of the cross section was carried out in the energy range of between 10 and 87 keV, and the obtaine...

Summary:The 13C(n,γ) 14C reaction cross section at stellar energy is crucial in studying the roles of the reaction in nucleosynthesis both in the early universe and in stellar helium burning. A new measurement of the cross section was carried out in the energy range of between 10 and 87 keV, and the obtained values are larger by a factor of about 10 compared to the values estimated from the thermal cross section with the 1 v law. The experimental results are shown, and the effects of the 13C(n,γ) 14C reaction on nucleosynthesis are discussed.
