On the thermal neutron scattering from polycrystalline vanadium

Abstract

The total cross section of polycrystalline vanadium is evaluated for neutron energies in the range 10 −3–20 eV, showing excellent agreement with the more recent experimental data. On the hypothesis of isotropy in the process, the scattering cross section is evaluated as a function of neutron energy. A variation of several percent is observed for this quantity over the energy range under consideration and the implications of this are briefly discussed for time-of-flight experiments.
