Experimental Study of Thick Target Yield from the ¹³C(α,n₀)¹⁶O Reaction

Abstract

The thick target neutron spectra from the ¹³C(α,n₀)¹⁶O reaction were measured for the energy range of 3.0 to 6.5 MeV at 10 angles in the laboratory angle interval of 0 to 150 deg. The thick target yield (TTY) was determined by integration of the neutron spectra over the neutron energy range corresponding to the ¹³C(α,n₀)¹⁶O reaction followed by integration of the obtained angular distribution of the differential TTY over the solid angle 4π. The content of ¹³C atoms in the target was determined by ion beam analysis with accuracy of <1%. The obtained TTY values support the calculated ones based on the ¹⁶O(n,α₀)¹³C reaction cross-section evaluation from the ENDF/B-VIII.0 library.
