Determination of thermal neutron radiative capture cross section of 6Li

The thermal neutron radiative capture cross section of 6Li was determined relative to the 1H(n,γ) reaction emitting the 2223.25 keV γ-ray. The sample used was a mixture of enriched 6Li2CO3 and melamine. Background correction was performed by considering the scattering effect of the sample. The determined thermal neutron radiative capture cross section of 6Li was 37.7 ± 3.0 mb.
