The thermal neutron radiative capture cross section of Li-6 was determined relative to the 1H(n,gamma) reaction emitting the 2223.25 keV gamma-ray. The sample used was a mixture of enriched (Li2CO3)-Li-6 and melamine. Background correction was performed by considering the scattering effect of the sample. The determined thermal neutron radiative capture cross section Of Li-6 was 37.7 +/- 3.0 mb. (c) 2005 Elsevier B.V. All rights reserved.
