Abstract

The ²³⁵U(n_th, α) reaction and the α-particles emitted in the thermal neutron induced fission of ²³⁵U were measured using a very pure thermal neutron beam of the Grenoble high flux reactor. An upper limit of 0.66 mb was determined for the ²³⁵U(n_th, α) reaction cross section, which is lower than all the previous results. The energy distribution of the α-particles produced by the ²³⁵U(n_th, f) reaction was measured down to 7 MeV with a non-shielded surface-barrier detector telescope assembly. The measured distribution has a quasi-Gaussian shape; it reveals, however, a pronounced deviation from such a shape at lower α-energies. Several possible explanations for this deviation are discussed.
