Abstract: We have measured energy angular distribution of secondary neutrons for 1) 7Li(p,xn) and 9Be(p,xn) reactions with thin targets at 70 MeV, 2)9Be(p,xn) reactions with a thick target at 11 MeV, using the time-of-flight technique at Tohoku University Cyclotron facility. Data were ob- tained at several laboratory angles from 0° to 110° using a beam swinger system and an NE213 scintillation detector placed at a well collimated neutron flight path. The energy range was from maximum to ∼4 MeV (at 70 MeV). The spectrum results at 70 MeV showed very strong angular dependence which should be considered in detail in the applied purposes, while the data at 11 MeV showed much milder dependence and in fair agreement with the prediction of MCNPX.
