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=ENGY-SPEC; ENR=>99%; CHM=ELM; PHYS-FORM=SLD; THK-TGT=634MG/CM**2; /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,5; INC-ENGY-LAB=346MEV; THTL=22DEG; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; TRNSF-ENGY'21' DSIGMA/DOMEGA/DE DELTA-DSIGMA/DOMEGA/DE (MEV) (MB/SR/MEV) (MB/SR/MEV) 25.0 0.7737 +-0.0021 30.0 0.9388 +-0.0023 35.0 1.1082 +-0.0025 40.0 1.2816 +-0.0027 45.0 1.4746 +-0.0029 50.0 1.6533 +-0.0030 55.0 1.8210 +-0.0032 60.0 1.9599 +-0.0033 65.0 2.0524 +-0.0034 70.0 2.1133 +-0.0034 75.0 2.1374 +-0.0034 80.0 2.1260 +-0.0034 85.0 2.1017 +-0.0034 90.0 2.0553 +-0.0034 95.0 2.0009 +-0.0033 100.0 1.9282 +-0.0033 105.0 1.8522 +-0.0032 110.0 1.7851 +-0.0032 115.0 1.7083 +-0.0031 120.0 1.6404 +-0.0030 125.0 1.5924 +-0.0030 130.0 1.5369 +-0.0029 135.0 1.4876 +-0.0029 140.0 1.4401 +-0.0028 145.0 1.4031 +-0.0028 150.0 1.3760 +-0.0028 155.0 1.3394 +-0.0027 160.0 1.3214 +-0.0027 165.0 1.3022 +-0.0027 170.0 1.2969 +-0.0027 175.0 1.2930 +-0.0027 180.0 1.2948 +-0.0027 185.0 1.2998 +-0.0027 190.0 1.3132 +-0.0027 195.0 1.3241 +-0.0027 200.0 1.3431 +-0.0027 \END; /*===================================================================*/ |
