Individual resonance parameters are fitted to thorium neutron capture data up to 10 keV. The ENDF/B-V resonance parameters (given up to 4 keV) do not describe these data well. An average radiation width Γ_γ = 25.5 ± 1.2 meV is derived together with fitted strength functions 10⁴S₀ = (0.86 ± 0.10), 10⁴S₁ = (1.48 ± 0.07), 10⁴S₂ = (1.12 ± 0.06), and D_l=0 = 14.7 ± 0.5.
