Abstract：
The gamma ray spectra from niobium under 14.9MeV neutron bombardments were neasured 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 gamma lines were determined by a high resolution gamma spectrum analysis program,and reaction types and transition levels of 62 lines were rudely assigned.There were 40 ones of 79 lines,which were first found in reactions induced by neutrons.The differential cross sections of every gamma line at 7 angles were determined.It is shown that associated gamma ray emission from this reaction are basically asotropic.
