A quasi-monoenergetic neutron field was developed using a thin ⁷Li target bombarded by protons in the energy range from 70 to 210MeV at the RIKEN ring cyclotron facility. The neutron energy spectra were measured with an NE213 organic liquid scintillator using the TOF method. The absolute peak neutron yields were obtained by measurements of 478keV γ-rays from ⁷Be nuclei produced in a ⁷Li target through the ⁷Li(p,n)⁷Be (g.s.+0.429MeV) reaction.
