F069900100005 AUTHOR (W.Weiss,W.Grum,J.W.Hammer,M.Koch,G.Schreder) F069900100006 INSTITUTE (2GERIFS) F069900100007 REFERENCE (J,NIM/A,292,359,1990) F069900100008 FACILITY (DYNAM) Stuttgart neutron scattering facility SCORPION.F069900100009 DETECTOR Four shielded neutron detectors (NE 213) were F069900100010 positioned and the range of the accessible reaction F069900100011 angles was between 21 and 124 degr. with a symmetric F069900100012 position of left and right detector. The minimum F069900100013 angular distance between two detectors was limited by F069900100014 the extension of the detector shielding to 42 degr. F069900100015 Two detectors were at a forward scattering angle F069900100016 of 50 degr and two detectors under a backscattering F069900100017 angle of 124 degr. F069900100018 METHOD (TOF) F069900100019 COMMENT All measurements were performed using high-pressure F069900100020 4He polarimeters. F069900100021 ERR-ANALYS (DATA-ERR) Definition error F069900100022 Energetic resolution varied between 12% (13C, 5.4 MeV) F069900100023 and 10% (9Be, 8.5 MeV). F069900100024 The errors of the present experiment could be kept F069900100025 small because of the use of the SCORPION facility F069900100026 favouring small systematic errors and the fourfold F069900100027 redundant measurement.
