The O173200100029 target windows were made of Mylar with a thickness of O173200100030 less than 1 mum. O173200100031 DETECTOR (MAGSP) The Big Karl magnetic spectrograph O173200100032 (MWDC) Two sets of multi-wire drift chambers for O173200100033 position measurement and track reconstruction. O173200100034 (SCIN) Scintillating hodoscopes, 4.5 m apart, led to O173200100035 a more accurate TOF measurements and provided the O173200100036 energy-loss information necessary for particle O173200100037 identification.

O173200100044 METHOD (TOF) O173200100045 COMMENT *By authors*.The experiment was carried out in two O173200100046 stages, first using an unpolarised beam.In order to O173200100047 extract an analyzing power, the beam polarisation had O173200100048 to be established and then used in the measurement of O173200100049 analyzing power. O173200100050 CORRECTION The peak areas were corrected for acceptance and O173200100051 converted into differential cross sections using the O173200100052 known luminosity.
