These polarimeters are separated by a bend angle of 98deg, thus the horizontal and vertical components of the polarization vector can be determined simultaneously. Each polarimeter consists of four arms of collimated pairs of confugate-angle plastic-scintillator telescopes. The polarimetry is based on the analyzing power of the 1H(p,p)1H scattering. /; /* Experimental Method: - Time-of-flight (To measure neutron energy) - Double scattering (To measure neutron polarization) RCT=208PB(P,N)X; PHQ=VCTR-ANALPW; ENR=>99%; CHM=ELM; PHYS-FORM=SLD; THK-TGT=634MG/CM**2; ANL=(PSHIFT-ANL'39',PSHIFT-ANL'40'); /* '39' D.V.Bugg and R.A.Bryan, phase-shift solution parametrized in the SAID program of Arnd and Roper, dated 1992. */ /* '40' R.A.Arndt and L.D.Roper, Scattering Analysis Interactive Dial-In program (SAID), phase-shift solution SP98, Virginia Polytechnic Institute and State University (unpublisehd). */ /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,15; INC-ENGY-LAB=346MEV; THTL=22DEG; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; TRNSF-ENGY'41' AY DELTA-AY (MEV) (NODIM) (NODIM) 25.0 0.263 +-0.004 30.0 0.248 +-0.003 35.0 0.246 +-0.003 40.0 0.237 +-0.003 45.0 0.236 +-0.003 50.0 0.220 +-0.003 55.0 0.220 +-0.002 60.0 0.209 +-0.002 65.0 0.207 +-0.002 70.0 0.204 +-0.002 75.0 0.199 +-0.002 80.0 0.188 +-0.002 85.0 0.190 +-0.002 90.0 0.184 +-0.002 95.0 0.176 +-0.002 100.0 0.173 +-0.002 105.0 0.166 +-0.002 110.0 0.160 +-0.002 115.0 0.154 +-0.003 120.0 0.146 +-0.003 125.0 0.141 +-0.003 130.0 0.132 +-0.003 135.0 0.132 +-0.003 140.0 0.120 +-0.003 145.0 0.116 +-0.003 150.0 0.105 +-0.003 155.0 0.097 +-0.003 160.0 0.093 +-0.003 165.0 0.082 +-0.003 170.0 0.074 +-0.003 175.0 0.064 +-0.003 180.0 0.064 +-0.003 185.0 0.056 +-0.003 190.0 0.050 +-0.003 195.0 0.037 +-0.003 200.0 0.033 +-0.003 \END; /*===================================================================*/ |
