Abstract Cross sections of the 10B(n,α)7Li reaction (including the total, the “leaking” alpha, forward alpha and backward alpha parts) at En =4.0 and 5.0 MeV were measured using an asymmetrical twin gridded ionization chamber and two back−to-back 10B samples. Measurements were performed at the 4.5 MV Van de Graaff accelerator of Peking University. Monoenergetic neutrons were produced through the 2H(d,n)3He reaction with a deuterium gas target. Absolute neutron flux was determined by a 238U sample set inside the gridded ionization chamber and a BF3 long counter was employed as a neutron flux monitor and for normalization. The present results are compared with previous measurements and evaluations.
