The thermal neutron capture cross section (σ0) and the resonance integral (I0) of 237Np have been measured by an activation method to supply basic data for the study of transmutation of nuclear waste. The neutron irradiation of 237Np samples have been done at the Research Reactor Institute, Kyoto University (KUR). Samples of 237Np were irradiated between two Cd sheets or without a Cd sheet. Since 237Np has a strong resonance at the energy of 0.49 eV, the Cd cut-off energy was adjusted at 0.358 eV (thickness of the Cd sheets: 0.125 mm). A high purity Ge detector was employed for activity measurement. The reaction rate to produce 238Np from 237Np was analyzed by the Westcott’s convention. Results obtained were 141.7±5.4 barns for σ0 and 862±51 barns for I0 above 0.358 eV of 273Np. By setting the Cd cut-off energy at 0.358 eV considering the resonance at 0.49 eV, a smaller value of σ0 was obtained in this work than the values reported by the previous authors.
