Spin observables of (d,p) reactions off $^{12}$C within the Paris potential

Deuteron elastic scattering off $^{12}$C is described in the framework of three-body Faddeev-type equations. Analyzing powers are calculated using the PEST16 potential which is a separable rank-one representation of the Paris potential. Satisfactory agreement with the experimental data is found.

$\overline{N}N$ ATOMS IN PARIS POTENTIAL

The [Formula: see text] atomic state problem is solved in a suitable numerical approach based on Sturmian functions, which is able to account for both the strong short range nuclear potential (for both the local and nonlocal) and the long range Coulomb force and to provide directly the wave function of protonium with complex eigenvalues [Formula: see text]. The small hyperfine-splittings and decay widths of the 1s and 2p levels of the [Formula: see text] atomic states are studied in the latest version of the Paris [Formula: see text] potential. It is found that the potential needs to be modified at energies around the [Formula: see text] threshold.

Analysis of light nuclei with the AMD method

The AMD simulation for light nuclei with realistic potentials, e.g. the Paris potential, is investigated. The results are in qualitatively good agreement with nuclear ground state energies. The framework provides a powerful tool for studying the structure of nuclei.

Evidence for three-body forces in p–d breakup at 25 MeV?

Experimental data for deuteron breakup by protons in collinear geometry at 25.00 MeV are compared with the predictions of rigorous Faddeev calculations using the Paris potential and with those of the Doleschall code. The Paris potential significantly underdetermines the breakup cross section in collinear geometry. The explanation for this discrepancy is not entirely clear at this time.
