“…As an example, we show in Fig. 2 a comparison between the Harwell data at 47.5 MeV and the Davis [56] and Karlsruhe [57] data at 50 MeV. As expected from the discussion above, the Harwell results are higher by about two standard deviations at forward angles and lower by about the same amount at backward angles.…”

“…[67] used a neutron beam with a continuous energy distribution [68] to measure simultaneously five angular distributions of the transverse spin correlation coefficient A between 18 and 50 MeV. This set of data complements the other Karlsruhe measurements of A [69] and do /dQ [57] over the same energy range.…”

“…New differential cross-section data in the backward hemisphere between 20 and 100 MeV were provided by Karlsruhe [57], Louvain-la-Neuve [59], and Uppsala [60], new analyzing power data by TUNL at 16 [66]. This observable is highly sensitive to E, and quite insensitive to 'P, [16].…”

Phase-shift analysis ofNNscattering below 160 MeV: Indication for a strong tensor force

A new phase-shift analysis of NN scattering in the energy range 15 -160 MeV is presented. The analysis is based on the carefully reviewed world pp +np data, including recent results for higher-order spin observables in n-p scattering. The latter are essential to determine the mixing parameter~& which is directly related to the isoscalar tensor force. c, displays a high trend, in agreement with recent analyses above 140 MeV, and is only reproduced by potential models with a strong tensor force. The prediction of the full Bonn potential is too low by 20% for energies above 40 MeV. All other I=O phase shifts show agreement with potential models; in particular, the notorious problem with 'P, around 50 MeV has disappeared. Around 25 MeV a ten parameter fit based purely on np data agrees with the corresponding At to the pp data and reveals no indication of anomalous charge independence breaking.PACS number(s): 21.30. +y, 13.75.Cs, 21.45. +v, 25. 10.+s

The matrix elements of relativistic nucleon-nucleon (NN) potentials are calculated directly from the nonrelativistic potentials as a function of relative NN momentum vectors, without using a partial wave decomposition. To this aim, the quadratic operator relation between the relativistic and nonrelativistic NN potentials is formulated in momentum-helicity basis states. It leads to a single integral equation for the two-nucleon (2N) spin-singlet state and four coupled integral equations for two-nucleon spin-triplet states, which are solved by an iterative method. Our numerical analysis indicates that the relativistic NN potential obtained using CD-Bonn potential reproduces the deuteron binding energy and neutron-proton elastic scattering differential and total cross-sections with high accuracy.
