Abstract：
Measurements of secondary neutron yields and angular distribution released by 80MeV electron incident on Pb thick target with moderated Indium foils are described. The angular distribution of neutron is isotropic and the yield is (2.20±0.13)×10¹²n/s. kW, these results agree with that of the theoretical calculation.
The possibility of using moderated Indium foil to measure the neutron field around the electron linear accelerator with energy less than 100MeV is also discussed, and the answer is positive.
