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=40CA(P,N)X; PHQ=POL; ENR=96.9%; CHM=ELM; PHYS-FORM=SLD; THK-TGT=359MG/CM**2; /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,12; INC-ENGY-LAB=346MEV; THTL=22DEG; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; TRNSF-ENGY'34' POL DELTA-POL (MEV) (NODIM) (NODIM) 25.0 0.256 +-0.020 30.0 0.247 +-0.018 35.0 0.220 +-0.016 40.0 0.222 +-0.014 45.0 0.263 +-0.013 50.0 0.232 +-0.012 55.0 0.231 +-0.011 60.0 0.217 +-0.011 65.0 0.227 +-0.010 70.0 0.209 +-0.010 75.0 0.213 +-0.010 80.0 0.226 +-0.010 85.0 0.211 +-0.010 90.0 0.211 +-0.010 95.0 0.221 +-0.010 100.0 0.211 +-0.010 105.0 0.220 +-0.010 110.0 0.207 +-0.010 115.0 0.203 +-0.010 120.0 0.227 +-0.011 125.0 0.216 +-0.011 130.0 0.199 +-0.011 135.0 0.199 +-0.012 140.0 0.217 +-0.012 145.0 0.211 +-0.013 150.0 0.194 +-0.013 155.0 0.197 +-0.013 160.0 0.220 +-0.014 165.0 0.214 +-0.014 170.0 0.170 +-0.015 175.0 0.184 +-0.015 180.0 0.197 +-0.015 185.0 0.195 +-0.016 190.0 0.143 +-0.016 195.0 0.156 +-0.017 200.0 0.160 +-0.018 \END; /*===================================================================*/ |
