The thickness of A121800100009 the stainless was 0.75 mm, and that of the gold 0.25 mmA121800100010 enriched deuterium gas was used through,at a A121800100011 pressure of about 500 mm Hg. A121800100012 DETECTOR (NAICR) The Stanford 24 cm * 24 cm A121800100013 CORRECTION Corrections were made for gamma-ray absorption in the A121800100014 wall of the gas cell and in paraffin and other A121800100015 shielding materials between cell and crystal, as well A121800100016 as for overall detector efficiency. A121800100017 ERR-ANALYS (ERR-T) Total error. Absolute cross sections are A121800100018 uncertain to 10-15%, shown in several points on fig. A121800100019 (ERR-1) The uncertainty due to absorption correction. A121800100020 (ERR-3) The uncertainty of detector efficiency and A121800100021 line-shape extrapolation. A121800100022 (ERR-4,2.,5.) The uncertainty of gas pressure (2-5%). A121800100023 (ERR-5) Uncertainty in the centering of the target. A121800100024 Improper shapes for the gamma(0) or gamma(1) decay A121800100025 spectra due to small inaccuracies in either the theory A121800100026 or the detector response function could also lead to A121800100027 significant systematic error in the relative size A121800100028 of the gamma(1) cross section. A121800100029 Cross sections at 90 degr. were measured for A121800100030 excitation energies in 5Li from 17.1 to 26.5 MeV.
