Polarization calculated from asymmetries 1019100100020 using P1 values given under INC-SPECT. 1019100100021 DETECTOR (SCIN) First detector NE102 plastic scintillator 1019100100022 described under sample. Second plastic scintillator 1019100100023 5.08 cm thick (theta direction), 19.1 cm wide (phi 1019100100024 direction), 7.62 cm deep. Similar detector also used 1019100100025 for some data at same angle in plane of other two. 1019100100026 Primary flux monitor magnetically shielded plastic 1019100100027 scintillator. 1019100100028 Source-scatter distance 125 cm.
