The 99Tc(n,γ) average cross section was measured at the Oak Ridge Electron Linear Accelerator from 2.65 to 2000 keV with an estimated uncertainty ranging from 4.0 to 4.9%. Individual resonance parameters were fitted by least-squares adjustment to the capture yield data from 2.65 to 5.08 keV. The average cross-section data agree with the ENDF/B-V (Mod 1) evaluation above 900 keV and lie within ±15% of the JENDL-1 evaluation below 700 keV.
