Analysis of measurements on the 99Tc(n,γ)100 and the Tc 99Tc(d,p)100Tc reactions leads to the conclusion that the determination of the inferred total thermal neutron capture cross section from partial capture cross sections necessarily has a large uncertainty at this time due to lack of accurate knowledge about the 100Tc level structure and decay scheme. A more precise value of the neutron binding energy of 100Tc of 6764.85 ± 0.25 keV was determined from the energies of the primary γ-rays.
