Two thin-film (10)B samples on tantalum backings were made for measurement of cross sections of the (10)B(n,α)(7)Li reaction in the MeV neutron energy region. The number of (10)B atoms in the samples was determined using the relative comparison method by detecting alpha and triton particles from thermal neutron induced nuclear reactions of (10)B(n(th),α)(7)Li and (6)Li(n(th),t)(4)He with a (6)LiF sample as the reference. A twin gridded ionization chamber was used as the detector of charged particles.
