“…The results obtained with other NN potentials at E d = 3 MeV deviate from the respective data more significantly. Furthermore, even if the reproduction of experimental binding energies is an important factor, it is certainly not the only one that matters because the linear correlation with 3N binding energies seems to be violated, for example, for iT 11 N3LO, CD Bonn, and CD Bonn + almost coincide despite quite significant differences (up to 0.4 MeV) in the respective 3N binding energies, while the predictions of INOY04 and AV18 stay well separated. A closer look into the calculated properties of deuteron, 3 He, and 3 H as given in Table I suggests that the considered spin observables correlate, in addition to the 3N binding energy, also with the D-state probability of deuteron P D (d).…”

“…There is a good agreement above E d = 2 MeV, while at lower energies, where the observable shows stronger energy dependence, the data points from Ref. [11] are slightly overpredicted. We include in Fig.…”

“…2-5 we present the corresponding results for the deuteron analyzing powers. The vector analyzing power iT 11 in Fig. 2 varies quite slowly with the energy.…”

“…The deuteron-to-neutron spin-transfer coefficient K y y has been measured in several experiments [10,11], however, only for the neutrons emitted in the forward direction c.m. = 0 • ; the data for the corresponding observable in the d + d → p + 3 H reaction are not available below the three-body breakup threshold.…”

“…Other observables that were measured but never analyzed through exact 4N calculations are polarization of the outgoing nucleon [9] and deuteron-to-nucleon spin-transfer coefficients [10,11]; they are also calculated in the present work.…”
