Simulation dataset of thermal and epithermal neutron self-shielding correction factors for 186W(n,γ)187W reaction rate experiments using tungsten foil targets.

In the experiments of neutron interaction with research samples, the incident neutron energy spectrum, distribution inside the irradiating sample volume, is affected by the unexpected neutron self-shielding effects. The nature of these effects is due to the formation and thickness of the irradiating sample, which significantly causes neutron self-absorption and multiple scattering inside the sample volume. The datasets presented in this article showed the thermal (G) and epithermal (G) neutron self-shielding correction factors for the W(n,γ)W neutron capture reaction rate in irradiating tungsten (W) foil samples with different thicknesses.
