In diameter X 2in. Thick) 2066100100042 on a xp1040 photomultiplier. 2066100100043 .The efficiency was determined by means of the N-P 2066100100044 scattering method.As scatterer served a polythylene 2066100100045 zylinder (1.5cm outer diameter,12.6g). 2066100100046 MONITOR .The cross section values were obtained 2066100100047 from the normalized counts in the corresponding 2066100100048 peaks of the time-of-flight spectra and by 2066100100049 comparison with the known N-P differential cross 2066100100050 section. 2066100100051 COMMENT .Optical and statistical model fits,using coupled- 2066100100052 channel and hauser/feshbach calculations,were 2066100100053 carried out for the presented experimental data and 2066100100054 data of other authors at lower energies(F.G.Perey 2066100100055 and W.E.Kinney,report ornl-4518(1970),P.Kuijper et 2066100100056 Al.,Nucl.Phys.,A181(1972,545). 2066100100057 STATUS .Differential elastic and inelastic cross section 2066100100058 data taken from cec-(73) 7. 2066100100059 CORRECTION .Both elastic and inelastic data were corrected for 2066100100060 attenuation. 2066100100061 .The elastic and first excited level data were also 2066100100062 corrected for multiple scattering. 2066100100063 .The corrections were carried out by means of the 2066100100064 MONTE CARLO method and also according to S.A.Cox, 2066100100065 nucl.Instr. And meth.56(1967),245. 2066100100066 .The inelastic data values represent an upper limit 2066100100067 because of the presence of a low energy tail in the 2066100100068 source neutron energy distribution. 2066100100069 ERR-ANALYS .Errors include statistical uncertainties and 2066100100070 uncertainties in the efficiency of the neutron 2066100100071 detector (+-10 % max.). 2066100100072
