Stopping samples of Lucite, Al, Fe, and /sup 238/U (Fe, and /sup 238/U) were irradiated with 330 MeV deuterons (260 MeV protons). For each target, neutron energy spectra and prompt ..gamma..-ray yields were measured using the time-of-flight technique. The detector was a right cylindrical volume of deuterated benzene, 12.5-cm diameter x 7.5-cm long, located at 110/sup 0/ to the incident beam direction. The neutron yield and the prompt ..gamma..-ray yield were found to depend upon the atomic number of the target and upon the incident projectile. The measured shape of the neutron energy spectrum was not strongly dependent on either the incident projectile or the target atomic number. A lower limit for absolute neutron yields was also obtained.
