Angular-distribution neutron-emission spectra of niobium following bombardment by fast neutrons

Conference ·
OSTI ID:5646020
;
Neutron-emission spectra at ten angles between 20 and 160/sup 0/ and incident neutron energies of 5.9, 7.1 and 8.4 MeV were measured relative to the neutron field emitted after spontaneous fission of /sup 252/Cf. The angular distribution of inelastically scattered neutrons appears to be essentially isotropic where it can be separated from the dominant elastic scattering peak. Above an excitation energy of 4 MeV the spectra are well described by a Maxwellian temperature distribution.
