The thermal neutron capture cross sections of Na23 and Mn55 have been determined using the activation method. The values are 0.53 ± 0.03 and 12.7 ± 0.3 barns respectively with respect to σAul97 = 93 barns. These agree well with recent pile oscillator results. The half-life for Mn56 is found to be 2.576 ± 0.002 hr.

The thermal neutron capture cross section of radioactive Au198 has been measured by the activation method as 26,000 ± 1200 barns, assuming 99 barns for the thermal neutron cross section of Au197. Metallic Au197 was bombarded in fluxes up to 9 × 1013 thermal neutrons cm.−2 sec.−1 to produce a mixture of Au198 and Au199 by the successive neutron capture reactions Au197(n, γ)Au198(n, γ)Au199. The ratio of the Au199 activity to Au198 activity so produced yields σc(Au197). In a preliminary experiment, the half-life of Au199 was measured as 3.148 ± 0.010 days.
