A measurement of the ⁵⁶Fe total neutron cross section at the interference minimum near 24.37 keV shows a value of 7.5 ± 4.2 mb. The data suggest a radiation width of 2 ± 1 eV for the 27.85-keV s-wave resonance of ⁵⁶Fe. The values Γ_n, = (1.43 ± 0.06) keV and R′ = (5.67 ± 0.16) × 10⁻¹³ cm [(5.67 ± 0.16) fm] for this resonance were deduced from a shape fit.
