“…As mentioned before, we aim at determining P Z alone, so for this purpose the vector analyzing power iT el 11 is of interest. That observable has been measured at the deuteron beam energies of 95 MeV and 106 MeV [62]. Slow variation of iT el 11 with energy validates the use of a linear interpolation of these data to the energy of 100 MeV.…”

Abstract. High-quality vector analyzing power data for the 1 H(d,pp)n breakup reaction and elastic scattering at 100 MeV beam energy have been measured in a large part of the phase space for these processes. The results are compared to theoretical predictions obtained using the charge-dependent Bonn potential alone or combined with the three-nucleon force TM99 as well as to the results of calculations in the coupled-channel approach, with or without the inclusion of the Coulomb interaction. In the studied observables, effects of the 3NF and the Coulomb force are almost absent. The pairwise NN interactions alone are sufficient to describe the experimental results.

Faddeev equations for elastic Nd scattering have been solved using modern NN forces combined with the Tucson-Melbourne two-pion exchange threenucleon force, with a modification thereof closer to chiral symmetry and the Urbana IX three-nucleon force. Theoretical predictions for the differential cross section and several spin observables using NN forces only and NN forces combined with three-nucleon force models are compared to each other and to the existing data. A wide range of energies from 3 to 200 MeV is covered. Especially at the higher energies striking three-nucleon force effects are found, some of which are supported by the still rare set of data, some are in conflict with data and thus very likely point to defects in those three-nucleon force models.

“…It was checked that in case of applying the full formula describing the N θ pol (ϕ) in the fit procedure, the obtained P zz component was consistent with zero, within the statistical [22], and earlier data sets: RIKEN data (red triangles) [23] and data from Ref. [24] error. Next, using the P z value obtained at one angular point, one can use the above outlined procedure to calculate the elastic scattering analyzing powers iT 11 at other experimentally covered angles.…”

Set of vector analyzing power data of the dp elastic scattering and 1 H ( d,pp)n breakup reactions at 130-MeV deuteron beam energy has been measured in the domain of very forward polar angles. The results are compared with theoretical predictions originating from various approaches: realistic nucleon-nucleon (NN) potentials and the NN potentials combined with a three-nucleon force (3NF) model and with predictions based on the ChPT framework. In case of the breakup process, none of the theoretical calculations reveal sensitivity to any of the dynamical effects such as 3NF or Coulomb interaction and they describe the experimental data equally well. For the elastic scattering, the Coulomb correction appears not negligible at very small θ c.m.d . The effect seems to be confirmed by the data. Few-nucleon systems are microscopic laboratories most suited for detailed study of the nucleon-nucleon (NN) interaction dynamics and the nuclear forces. Among them, the system composed of three nucleons (3N) is the simplest nontrivial environment where NN force models can be tested. Properties of 3N systems at medium energies are mainly determined by pairwise NN interaction. There are, however, reasons to assume the existence of additional dynamical effects like three-nucleon force (3NF) related to the presence of the third nucleon, or the Coulomb interaction, very significant in the domain of small polar angles of the emitted protons. Both effects are modeled within different theoretical formalisms.The realistic two-nucleon (2N) forces can be combined with the recent version of the 2π -exchange Tucson-Melbourne (TM) 3NF [1] or in the case of AV18 NN force with the Urbana IX 3NF [2]. Alternatively, 3NF can be generated by an explicit treatment of the isobar excitation within the coupled channel (CC) method [3]. For the 3N system, creation of a -containing state yields an effective 3NF but also two-barion dispersion. These two effects usually compete, and therefore * izabela.ciepal@uj.edu.pl the net effects of including the isobar in the potential are smaller than for approaches with the phenomenological 3NF's. When the chiral perturbation theory (ChPT) is used at the next-to-next-to-leading order (NNLO), the 3N contributions arise naturally, fully consistently with the NN force terms [4].The long-range electromagnetic component of the NN interaction was successfully implemented in CC formalism [5,6] as well as in the calculations [7] based on the AV18 NN potential combined with the Urbana IX 3NF.Besides the binding energies of the light nuclei, the importance of the 3NF was experimentally confirmed on the basis of the data originating from the nucleon-deuteron elastic scattering process [8][9][10][11][12][13][14][15][16][17]. In general, inclusion of the 3NF component improves the description of the cross-sectional data. However, quite significant discrepancies between the theoretical models and polarization observables are still present. Exploration of the nucleon-deuteron breakup can be considered as a natural next step in the...
