DOUBLE DIFFERENTIAL NEUTRON EMISSION CROSS SECTION FOR THE 7-LI(N,XN) REACTION BETWEEN 1,6-16 MEV.
A neutron spectrometer for the measurement of double differential neutron emission cross sections has been set up. The electron linac GELINA was used as a pulsed white neutron source. The energy of the incident neutrons was determined by the time-of-flight method with a source to sample distance of 60 m. The secondary neutron spectra were determined by unfolding the pulse height distribution as observed in six NE-213 scintillators (diameter = 5 cm, h = 5 cm) located at 20 cm from the sample. Here we present preliminary results for the 7-Li(n,Xn) reaction obtained with a thin sample (0.0325 at/b) for emission angles THETA = 24, 60, 90, 120, 150, 160 degree and for incident neutron energies between 1,6 and 16 MeV. The data have been normalized to the shape of the incident neutron flux as determined with an 235-U fission chamber. The absolute values are based on the differential elastic cross section of 12-C below 2 MeV.
