Proton−deuteron elastic scattering above the deuteron breakup
نویسندگان
چکیده
The complex Kohn variational principle and the (correlated) hyperspherical harmonics method are applied to study the proton–deuteron elastic scattering at energies above the deuteron breakup threshold. Results for the elastic cross section and various elastic polarization observables have been obtained by taking into account the long–range effect of the Coulomb interaction and using a realistic nucleon–nucleon interaction model. Detailed comparison to the accurate and abundant elastic proton–deuteron experimental data can now be performed.

The complex Kohn variational principle and the (correlated) hyperspherical harmonics method are applied to study the proton–deuteron elastic scattering at energies above the deuteron breakup threshold. Results for the elastic cross section and various elastic polarization observables have been obtained by fully taking into account the long–range effect of the Coulomb interaction and using a rea...
متن کاملFew-body Systems Proton-deuteron Elastic Scattering for E > 0
We report on the rst reliable numerical results for proton-deuteron elastic scattering observables for energies above the deuteron breakup threshold , for the Paris potential. The calculations have been performed within the screening and renormalisation approach. The theoretical results are compared with experimental data of Sagara et al.
متن کاملPhase Shifts and Mixing Parameters for Elastic Proton-Deuteron Scattering
The eigenphase shifts and mixing parameters for elastic p-d scattering below the deuteron-breakup threshold are calculated for the AV14 two-body potential using two different numerical methods. The excellent agreement confirms that it is possible to perform accurate numerical studies of p-d scattering as well as n-d scattering for low energies. The numerical results can be considered as benchma...

In this paper, we reformulate three-nucleon breakup scattering in leading order approximation by considering spin-isospin degrees of freedom. At first, considering the inhomogeneous part of Faddeev equation, which is a valid approximation in high and intermediate energles, we present the Faddeev equation as a function of vector Jacobi momenta and spin and isospin quantum numbers. In this new fo...
متن کاملLow Energy Proton-Deuteron Scattering in Configuration Space
A new method for solving the configuration-space Faddeev equations for elastic p-d scattering below the deuteron-breakup threshold is described. Numerical solutions that demonstrate the convergence and accuracy of the method are given. The number of channels and the value of the matching radius required to obtain an accurate solution are also investigated. It is shown that this method can be us...
