The effective neutron energy of 98 +- 3 MeV 2177800100014 quoted in the common section was calculated from a 2177800100015 measurement of the attenuation of the beam by 2177800100016 polythene. 2177800100017 SAMPLE .Polythene and carbon samples. 2177800100018 METHOD .Asymmetry of scattered neutrons calculated from 2177800100019 counting rates at zero and ninety degrees 2177800100020 azimuthal angle. 2177800100021 DETECTOR (TELES,SCIN,SCIN) Counter telescope was mounted on a 2177800100022 movable arm which clamped to the table. Each plastic 2177800100023 scintillator was mounted in a perspex light guide in a 2177800100024 rigid metal frame and had inscribed at its centre a 2177800100025 small cross for alignment. The defining crystal al was 2177800100026 1.5 cm x 6.0 cm and 0.3 cm thick a placed at distance 2177800100027 from the scatterers. 2177800100028 MONITOR The monitor used was a trip triple coincidence proton 2177800100029 recoil telescope. It was similar to the counter 2177800100030 telescope so that the effect of small cyclotron energy 2177800100031 variations was largely cancelled out. Proton recoils 2177800100032 originated in a polythene radiator 1 cm thick placed 2177800100033 immediately after the collimator. 2177800100034 A boron trifluoride slow neutron counter near the 2177800100035 apparatus was also used as a monitor throughout the 2177800100036 experiment as an additional check on the behaviour of 2177800100037 the equipment. 2177800100038 CORRECTION .Geometric asymmetries. 2177800100039 .Effect of the cyclotron magnetic field on 2177800100040 the scattering. 2177800100041 .Asymmetries in background count rates. 2177800100042 ERR-ANALYS (DATA-ERR) The major contribution is from counting 2177800100043 statistics.
