Precise measurements of total neutron cross sections are proposed by using an Fe-filtered beam and a proton-recoil counter. An accuracy of 0.3% was realized for the 24-keV cross sections of Be and C.<BR>It is important that an Fe-filtered beam has a low contamination of both backgrounds of other energy neutrons and γ-rays of all energies. The backgrounds were accurately determined by a Ti-filter of 4 cm in thickness.
