Energy and angular distribution of deutrons emitted in the interaction of 9.1+-0.2 MeV neutrons with U-238 nuclei

The spectra of secondary neutrons arising due to interaction of the neutrons having initial energy of 9.1+-O.2 MeV with U-238 are measured under the angles of 30 deg, 60 deg, 90 deg, 120 deg, 150 deg by means of the time-of-flight method at the 150 cm cyclotron. The twice differential sections of interaction of neutrons with nuclei of U-238 are determined. The integral spectrum of the neutrons from reactions(n,n') and (n, 2n) is analysed in framework of the pre-equilibrium model
