The neutrons were obtained by 2002700100010 bombarding a tritium gas target 3 cm long, filled to 2002700100011 a pressure of 0.8 kp/cm2. The mean current on the 2002700100012 target was about 0.8 mu-A in most experiments. 2002700100013 INC-SPECT (EN-RSL-HW) The total neutron energy 2002700100014 spread was +- 40 keV 2002700100015 SAMPLE The scatterers were cylinders of natural elements with2002700100016 2.5 cm outer diam., 0.9 cm inner diam., and an axial 2002700100017 thickness of 2.5 cm, positioned with their axis 2002700100018 perpendicular to that of the detector. 2002700100019 METHOD (TOF) Time-of-flight 2002700100020 DETECTOR (NAICR) Sodium-iodide crystal.
