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=12C(P,N)X; PHQ=ENGY-SPEC; ENR=98.9%; CHM=ELM; PHYS-FORM=SLD; THK-TGT=260MG/CM**2; /*===================================================================*/ /* Descriptive Parameters */ /*===================================================================*/ \\DATA,3; INC-ENGY-LAB=346MEV; THTL=22DEG; /*===================================================================*/ /* Data Table */ /*===================================================================*/ \DATA; TRNSF-ENGY'19' DSIGMA/DOMEGA/DE DELTA-DSIGMA/DOMEGA/DE (MEV) (MB/SR/MEV) (MB/SR/MEV) 25.0 0.3012 +-0.0005 30.0 0.2342 +-0.0005 35.0 0.2544 +-0.0005 40.0 0.2867 +-0.0005 45.0 0.3252 +-0.0005 50.0 0.3660 +-0.0006 55.0 0.4045 +-0.0006 60.0 0.4351 +-0.0006 65.0 0.4591 +-0.0006 70.0 0.4757 +-0.0007 75.0 0.4861 +-0.0007 80.0 0.4878 +-0.0007 85.0 0.4820 +-0.0007 90.0 0.4716 +-0.0007 95.0 0.4549 +-0.0006 100.0 0.4342 +-0.0006 105.0 0.4116 +-0.0006 110.0 0.3866 +-0.0006 115.0 0.3626 +-0.0006 120.0 0.3392 +-0.0005 125.0 0.3171 +-0.0005 130.0 0.2977 +-0.0005 135.0 0.2783 +-0.0005 140.0 0.2604 +-0.0005 145.0 0.2457 +-0.0005 150.0 0.2323 +-0.0005 155.0 0.2221 +-0.0004 160.0 0.2108 +-0.0004 165.0 0.2029 +-0.0004 170.0 0.1956 +-0.0004 175.0 0.1888 +-0.0004 180.0 0.1845 +-0.0004 185.0 0.1799 +-0.0004 190.0 0.1764 +-0.0004 195.0 0.1737 +-0.0004 200.0 0.1715 +-0.0004 \END; /*===================================================================*/ |
