چکیده

A new measurement of the p-d differential cross section at Ep = 1 MeV has been performed. These new data and older data sets at energies below the deuteron breakup are compared to calculations using the two–nucleon Argonne v18 and the three–nucleon Urbana IX potentials. A quantitative estimate of the capability of these interactions to describe the data is given in terms of a χ analysis. The χ per datum drastically improves when the three-nucleon interaction is included in the Hamiltonian.

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...

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...

Precise measurement of dp elastic scattering at 270 MeV and three-nucleon force effects

The cross section, the deuteron vector A(d)(y) and tensor analyzing powers A(ij), the polarization transfer coefficients K(y('))(ij), and the induced polarization P(y(')) were measured for the dp elastic scattering at 270 MeV. The cross section and A(d)(y) are well reproduced by Faddeev calculations with modern data-equivalent nucleon-nucleon forces plus the Tucson-Melbourne three-nucleon force...

The A(y) problem for p-3He elastic scattering.

We present evidence that numerically accurate quantum calculations employing modern internucleon forces do not reproduce the proton analyzing power, A(y), for p- 3He elastic scattering at low energies. These calculations underpredict new measured analyzing powers by approximately 30% at E(c.m.) = 1.20 MeV and by 40% at E(c.m.) = 1.69 MeV, an effect analogous to a well-known problem in p-d and n...

Analyzing power in nucleon-deuteron scattering and three-nucleon forces

Three-nucleon forces have been considered to be one possibility to resolve the well known discrepancy between experimental values and theoretical calculations of the nucleon analyzing power in low energy nucleondeuteron scattering. In this paper, we investigate possible effects of twopion exchange three-nucleon forces on the analyzing power and the differential cross section. We found that the ...
