Abstract
The thermal neutron capture cross section and the resonance capture integral of Th230 have been determined by an activation method. Assumptions are made that the thermal capture cross section and the resonance capture integral of Co59 are 36.5 barns and 48.6 barns respectively, that the half-life of Th230 is 8.00 × 104 years, and that Th230 behaves as a 1/v absorber in the subcadmium region. Based on these assumptions values of σ2200 = 21.4 ± 0.3 barns and of 937 ± 32 barns for the resonance absorption integral (from 0.5 ev to ∞) have been obtained for Th230.The half-life of Th231 has been determined as 25.52 ± 0.01 hours.
