Abstract The neutron energy spectrum of a 241 Am-Be (_,n) source was measured by means of a 3 He spectrometer in the energy range from 100 keV to 11 MeV. The spectrometer consisted of two semiconductor detectors with a proportional counter arranged between them to measure the energy loss of the 3 He (n,p) 3 H reaction particles in the 3 He gas.
