DOUBLE-DIFFERENTIAL NEUTRON EMISSION SPECTRA FOR Al, Ti, V, Cr, Mn, Fe, Ni, Cu, and ZrDepartment of Nuclear Engineering, Tohoku University, Sendai 980, Japan The angle-dependent neutron emission spectra have been measured for nuclides cited above at the incident neutron energy of 14.1 MeV. For aluminum, iron, nickel, copper and zirconium, the measurements were performed as well at 18 MeV incident energy. The data were obtained at 7-12 laboratory angles for secondary neutrons down to 0.6 MeV. The emission neutrons show systematic angle dependence and their angular distribution were compared favorably with the calculation based on the Kalbach-Mann systematics.
