Making use of the time-of-flight method, the inelastic scattering spectra of neutrons in the energy range of 0.6 to 4.0 Mev were determined by bombarding natural isotopic mixtures of Na, Fe, Ni and Pb with 14-Mev neutrons. The experimental arrangement consisted of a pulsed source, neutron detectors and the apparatus needed for time-of-fiight measurements. The source was operated at a frequency of 500 hertz with 2.5 - 10/sup -8/ sec neutron pulses and a flight distance of 6 m; a liquid xylene scintillator was used as detector. The spectra were analyzed on a 128channel amplitude analyzer. The temperature, T, of the residual nucleus, calculated from the relationship (dN/dE) approximates Ee/sup -E/ T/, gave the following results: Na, 0.97 approximately 0.09; Fe, 0.80 plus or minus 0.08; Ni, 0.79 plus or minus 0.08; Pb, 0.75 plus or minus 0.08 Mev. The data for Fe and Pb agree quite well with available literature data. (TTT)
