E192500100015 INC-SOURCE Beam intensity is about 400 nA. E192500100016 INC-SPECT - EN: Value at the center of target E192500100017 - [EN-RSL] Energy loss of incident deuterons E192500100018 SAMPLE - Target enrichment is 99%. E192500100019 - Chemical-form of target is element. E192500100020 - Physical-form of target is solid. E192500100021 - Target-thickness is about 40 mg/cm**2. E192500100022 - Target is self supported. E192500100023 METHOD (DSCAT) Liquid helium polarimeter [M. Yamaguchi et E192500100024 al., Nucl. Instrum. Meth. A506(2003)35]. E192500100025 Efficiency was about 2.0e-4 and effective E192500100026 analyzing power was -0.43+-0.02 at a proton E192500100027 energy of 22 MeV.

Rep. 54(1987)5] E192500100031 ERR-ANALYS (ERR-S) Statistical uncertainty E192500100032 (ERR-SYS) Total systematic error of proton E192500100033 polarization (=asymmetry / effective E192500100034 analyzing power) includes those of asymmetry E192500100035 and effective analyzing power. Error in the E192500100036 asymmetry includes (1) the effect of the E192500100037 anisotropic angular distribution of emitted E192500100038 protons, (2) the uncertainty in the E192500100039 scattering angle and solid angle due to a E192500100040 horizontal shift of the proton focal spot in E192500100041 polarimeter. Error in the effective E192500100042 analyzing power includes same errors as E192500100043 asymmetry as well as the systematic error of E192500100044 polarization used to derive effective E192500100045 analyzing power of polarimeter.
