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=ENGY-SPEC; ENR=96.9%; CHM=ELM; PHYS-FORM=SLD; THK-TGT=359MG/CM**2; /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,4; INC-ENGY-LAB=346MEV; THTL=22DEG; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; TRNSF-ENGY'20' DSIGMA/DOMEGA/DE DELTA-DSIGMA/DOMEGA/DE (MEV) (MB/SR/MEV) (MB/SR/MEV) 25.0 0.2600 +-0.0007 30.0 0.3131 +-0.0008 35.0 0.4176 +-0.0009 40.0 0.5104 +-0.0010 45.0 0.5968 +-0.0011 50.0 0.6746 +-0.0012 55.0 0.7351 +-0.0012 60.0 0.7818 +-0.0012 65.0 0.8171 +-0.0013 70.0 0.8407 +-0.0013 75.0 0.8553 +-0.0013 80.0 0.8624 +-0.0013 85.0 0.8595 +-0.0013 90.0 0.8530 +-0.0013 95.0 0.8369 +-0.0013 100.0 0.8156 +-0.0013 105.0 0.7885 +-0.0012 110.0 0.7588 +-0.0012 115.0 0.7284 +-0.0012 120.0 0.6930 +-0.0012 125.0 0.6576 +-0.0011 130.0 0.6242 +-0.0011 135.0 0.5949 +-0.0011 140.0 0.5659 +-0.0010 145.0 0.5409 +-0.0010 150.0 0.5180 +-0.0010 155.0 0.4988 +-0.0010 160.0 0.4813 +-0.0010 165.0 0.4685 +-0.0010 170.0 0.4536 +-0.0009 175.0 0.4467 +-0.0009 180.0 0.4398 +-0.0009 185.0 0.4337 +-0.0009 190.0 0.4324 +-0.0009 195.0 0.4279 +-0.0009 200.0 0.4288 +-0.0009 \END; /*===================================================================*/ |
