| Research Abstract |
The neutron energy spectra of carbon, iron, and gold targets with 140 MeV protons at 180° were measured at the RCNP cyclotron facility using the time-of-flight technique. Experimental neutron energy spectra at 180° were composed of two evaporation Maxwellian-type components (in two neutron energy regions of 1-4 MeV and 4-10 MeV) and a pre-equilibrium (in the neutron energy region above 10 MeV) Maxwellian-type component. All experimental spectra were fitted well by the sum of three Maxwellian-type equations across the entire energy region of the neutrons.
