Abstract：
The gamma-ray spectra from niobium under 14.9 MeV neutron bombardments were measured by means of a pulsed T(d,n)⁴He neutron source, associated particle method, Ge(Li) detector and time-of-flight technique at 7 angles between 30° and 140°. 79 gammalines were determined by a high resolution gamma-spectrum analysis program. The reaction types and the transition levels of 62 lines were preliminarily assigned. Of the 79 gamma-lines, 40 lines were first found in the reactions induced by neutrons. The differential cross sections of every gamma-line at 7 angles were determined. Our study shows that the associated gamma-ray emissions from this reaction are basically isotropic.
