Polarization in the elastic scattering at backward angles of 30 MeV protons from deuterons

Energy dependence of the three-nucleon analyzing power puzzle

“…Figures 1(b)-(h) summarize N-d A y (θ ) data in the energy range between 18 and 35 MeV. Except for the n-d data at E n = 30 MeV of Dobiasch et al [7], all other data are for p-d scattering [2][3][4][5][6]8]. The 3N calculations are from Witała [12], Kievsky [13] and Deltuva [31].…”
