Sažetak
Instrumental asymmetries recently observed by Haeberli and co-workers, limit the accuracy of neutron-proton analyzing power Ay(θ ) data. These instrumental effects are discussed and calculated for previously published n-p Ay(θ ) data at 16.9 MeV. To enable these calculations, the analyzing power for the 2H(d→ , n)3He reaction was measured at small angles. Additional n-p Ay(θ ) data at extreme backward angles, obtained via proton recoil detection, are also reported for this energy in this paper. The composite data set is compared to calculations based on the new Bonn NN potential, the Paris NN potential, and to the recent NN phase-shift solution of Arndt. In addition, a detailed comparison between Ay(θ ) calculated from the new Bonn and the Paris potentials between 10 and 50 MeV is shown to reveal unexpectedly large relative differences. The experimental data in this energy range are better described by the Paris potential than by the new Bonn potential.
