Neutron energy practically independent of 1379000100010 deuteron energy in the interval studied (50-300 keV). 1379000100011 METHOD Transmission. 1379000100012 DETECTOR (IOCH) Paraffin-lined ionization chamber of 2.5 cm 1379000100013 diameter placed 27 cm from the target. 1379000100014 CORRECTION Results corrected for: 1379000100015 . neutrons scattered into chamber from parts of the 1379000100016 apparatus near target (about 3% of the total yield 1379000100017 at 27 cm). 1379000100018 . neutrons scattered into chamber from scatterer 1379000100019 (few percent of measured transmission).
