Neutrons from the bombardment of beryllium by deuterons

Abstract
Fast neutron spectra produced by the bombardment of thin and thick beryllium targets with deuterons have been measured at incident energies between 3 and 18 MeV. Total neutron yields and average neutron energies were determined from the data. The purpose of the measurements was to provide information from which dose rates and depth dose can be calculated for various conditions encountered in neutron radiotherapy with cyclotrons.
