FACILITY   (VDGT,1USATNL)The deuteron beam was accelerated by     1424000100014 
           way of the model FN Tandem Van de Graaff accelerator   1424000100015 
SAMPLE     The target used for this experiment consisted of a     1424000100016 
           6.86 g rectangular 238U foil (3.65 x 5.20 x 0.02 cm)   1424000100017 
           backed by rectangular foils of 99.5% natural iron      1424000100018 
           with thickness of 0.0038 cm and positioned in the      1424000100019 
           neutron beam 215 cm downstream from the gas cell.      1424000100020 
DETECTOR   (HPGE). Gamma rays emitted from the target were        1424000100021 
           measured using a set of clover and planer HPGe         1424000100022 
           detectors, each equipped with a bismuth germinate      1424000100023 
           suppression shield and NaI nose cone. The detectors    1424000100024 
           were mounted on movable stands that rotated about      1424000100025 
           the target position in the horizontal plane and        1424000100026 
           allowed measurements at laboratory angles ranging      1424000100027 
           from 0. to 140 deg.                                    1424000100028 
METHOD     (TOF)Time of flight was used to separate prompt        1424000100029 
           gamma rays.                                            1424000100030 
INC-SOURCE (D-D)Fast neutrons were produced via the 2H(d,n)3He    1424000100031 
           reaction by bombarding a deuterium gas cell with an    1424000100032 
           accelerated beam of deuterons.The system provide up    1424000100033 
           to 3 mu-A of pulsed deuteron current with a pulse      1424000100034 
           width of 2 ns and a repetition rate of 2.5 MHz or      1424000100035 
           smaller (by factors of 2).The deuteron beam was        1424000100036 
           accelerated by way of the model FN Tandem Van de       1424000100037 
           Graaff accelerator before bombarding a cylindrical     1424000100038 
           gas cell pressurized to 7.8 atm with 99.999% pure      1424000100039 
           deuterium gas.Deuteron ions entered the cell through   1424000100040 
           a 6.35 mu-m Havar foil.                                1424000100041
