Abstract：
The differential cross section of fast neutrons on ⁶Li and ⁷Li has been measured at 14.7MeV using associated particle time-of-flight technique.Scattered neutrons are detected at 9 angles from 35 to 115 deg in massively shielded ST451 liquid scintillator located 254cm from the scattering sample.The efficiency curve of neutron detector was determined by measuring the n-p scattering in polyethylence. The total error of the differential cross section is from 10% to 15% including the statistical error of 1.0-5.0%and the measurment error of efficiency curve of 6.0%7.5 %.
