Total Cross Sections of Ti, V, Y, Ta, and W

Total neutron cross sections have been measured by the transmission method for metal samples of Ti, V, Y, Ta, and W in the energy range from 0.002 to 0.285 ev. The present data are in agreement, within experimental error, with the previously published data at energies for which a comparison can be made. Absorption cross sections for 0.0253-ev neutrons, obtained by fitting a 1/v line to the total cross section at cold neutron energies, give 20 ± 0.9 and 18.8 ± 0.8 barns for Ta and W, respectively.
