The total neutron cross section for four different samples of normal boron was measured at neutron energies between 0.00291 and 0.1 ev. The absorption cross section was obtained by subtracting the relatively small known scattering cross section. The B/sup 10/ content of three of the samples was measured with a mass spectrometer. Values of 764 plus or minus 3, 761 plus or minus 3, 764 plus or minus 3, and 762 plus or minus 3 barns were obtained for the four samples. (M.C.G.)
