0 Elastic p − 3 He and n − 3 H scattering with two - and three - body forces
نویسندگان
چکیده
We report on a microscopic calculation of n−H and p−He scattering employing the Argonne v18 and v ′ 8 nucleon-nucleon potentials with and without additional three-nucleon force. An Rmatrix analysis of the p−He and n−H scattering data is presented. Comparisons are made for the phase shifts and a selection of measurements in both scattering systems. Differences between our calculation and the R-matrix results or the experimental data can be attributed to only two partial waves (P0 and P2). We find the effect of the Urbana IX and the Texas-Los Alamos three-nucleon forces on the phase shifts to be negligible.

It is shown that owing to a dominance of np−pair transfer mechanism of backward elastic p 3 He-scattering for incident proton kinetic energies T p > 1 GeV the cross section of this process is defined mainly by the values of the Faddeev component of the wave function of 3 He nucleus, ϕ 23 (q 23 , p 1), at high relative momenta q 23 > 0.6GeV /c of the NN-pair in the 1 S 0 − state and at low spect...

The Kohn variational principle and the (correlated) Hyperspherical Harmonics technique are applied to study the n − 3 H and p − 3 He scattering at zero energy. Predictions for the singlet and triplet scattering lengths are obtained for non–relativistic nuclear Hamiltonians including two– and three– body potentials. The calculated n− 3 H total cross section agrees well with the measured value, w...

Available data on large-angle nucleon-deuteron elastic scattering N d → dN below the pion threshold give a signal for three-body forces. There is a problem of separation of possible subtle aspects of these forces from off-shell effects in two-nucleon potentials. By considering the main mechanisms of the process N d → dN , we show qualitatively that in the quasi-binary reaction N + d → (N N) + N...
متن کاملSizes of the He isotopes deduced from proton elastic scattering measurements
Glauber theory provides a microscopic formulation of reactions of composite nuclei at high energies. Two approaches, recently used for the treatment of the proton–He systems, are discussed and contrasted. The observed sensitivity of few-body calculations to the nuclear size and structure inputs used is discussed. It has been demonstrated that reaction calculations which include an explicit trea...
