Abstract

The thermal neutron induced (n, α) reaction cross sections of ²³³U, ²³⁵U and ²³⁸U were measured using a highly pure thermal neutron beam from the Grenoble High Flux Reactor. In the case of the ²³⁸U(n_th, α) ²³⁵Th reaction, a Q_α value of 8.70 ± 0.05 MeV, a ²³⁵Th mass of 235.04751 ± 0.00006 amu and a Q_β value of 1.92 ± 0.16 MeV (for the β-decay of ²³⁵Th) were determined. Also statistical model calculations of the (n, α) cross section were performed which were in poor agreement with the measured value.
