| Abstract: | The response of a gridded 3He ionization chamber to monoenergetic neutrons has been calculated using a Monte Carlo approach. The effects of neutron scattering on detector materials, wall effects, recoil continua and background neutrons are included. The calculated results are smoothed according to a peak shape taken from experiment. Response functions in the energy range En < 1217 keV are compared to experimental data obtained with the 7Li(p, n)7Be reaction and to the detector efficiency derived from them. |
