چکیده

Developments in spin-polarized internal targets for storage rings have permitted measurements of 197 MeV polarized protons scattering from vector polarized deuterons. This work presents measurements of the polarization observables A(y), iT11, and C(y,y) in proton-deuteron elastic scattering. When compared to calculations with and without three-nucleon forces, the measurements provide further evidence that three-nucleon forces make a contribution to the observables. This work indicates that three-body forces derived from static nuclear properties appear to be crucial to the description of dynamical properties.

اندازه‌گیری مشاهده‌پذیرهای کانال تجزیه سه‌جسمی برای بخشی از فضای فاز پراکندگی دوترون- دوترون در انرژی برنوکلئون

Information obtained from nucleus as a bound system of nucleons and from nucleon-nucleon scattering experiments is a strong tool for studying various aspects of nuclear forces. Deuteron-deuteron scattering as a four-nucleon system can provide useful information. So, scattering experiment of a polarized beam of deuteron with kinetic energy of65 MeV/nucleon from a liquid-deuterium target was done...

Proton−deuteron elastic scattering above the deuteron breakup

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...

Cross Section Minima in Elastic Nd Scattering: Possible Evidence for Three-Nucleon Force Effects

Neutron-deuteron elastic scattering cross sections are calculated at different energies using modern nucleon-nucleon (NN) interactions and the Tucson-Melbourne three-nucleon force adjusted to the triton binding energy. Predictions based on NN forces only underestimate nucleon-deuteron data in the minima at higher energies starting around 60 MeV. Adding the three-nucleon forces fills up those mi...

Low Energy Proton-Deuteron Scattering with Exact Treatment of Coulomb Force

A modified version of the Faddeev three-body equation to accommodate the Coulomb interaction, which was used in the study of three-nucleon bound states, is applied to the proton-deuteron scattering problem at energies below the three-body breakup threshold. A formal derivation of the equation in a time-independent scattering theory is given. Numerical results for phase shift parameters are pres...
