Gamma-ray production cross sections have been measured for the (n,x..gamma..) reactions in Al, Ni, Cu, and Nb at the neutron energies of 5.3, 5.9, 6.4 and 7.0 MeV. The Dynamitron accelerator and a deuterium gas target were used to produce pulsed monoenergetic neutrons. Gamma-rays were detected with a heavily shielded 70-cm/sup 3/ coaxial Ge(Li) detector placed at an angle of 125/sup 0/. A time-of-flight technique was adopted to discriminate against pulses due to scattered neutrons and background radiations. Absolute cross sections of discrete gamma-ray lines are obtained. Total and unresolved gamma-ray production cross sections are also obtained by unfolding the pulse height spectra with a modified FERDOR code. The present results are discussed in comparison with previous data, and are in general agreement with those of ORNL.
