Based on analyses of previous experimental methods and results, the cross sections of the {sup 186}W(n, {gamma}){sup 187}W reaction were measured in the neutron energy range from 0.50 to 1.50 MeV by the activation technique. Neutrons were produced through the T(p,n){sup 3}He reaction, and the cross sections of the {sup 197}Au(n, {gamma}){sup 198}Au reaction were used to determine the absolute neutron flux. Experimental results agreed with the previous time-of-flight measurements but did not agree with the previous activation measurements. Without the tungsten resonance absorption foils, the measured cross sections of the {sup 186}W(n, {gamma}){sup 187}W reaction by the activation method were shown to be larger than the corrected ones because of the interference of the low-energy neutrons.
