Abstract
High-precision measurements of the scattering observables such as cross sections and analyzing powers for the proton-deuteron elastic and break-up reactions have been performed at KVI in the last two decades and elsewhere to investigate various aspects of the three-nucleon force (3NF) effects simultaneously. In 2006 an experiment was performed to study these effects in $\vec{p}+d$ break-up reaction at 135 MeV with the detection system, Big Instrument for Nuclear polarization Analysis, BINA. BINA covers almost the entire kinematical phase space of the break-up reaction. The results are interpreted with the help of state-of-the-art Faddeev calculations and are partly presented in this contribution.
Highlights
In the last few decades, several nucleon-nucleon potentials (NNPs) have been studied extensively to describe the properties of bound nuclear systems by comparing highprecision two-nucleon scattering data with modern potentials based on the exchange of bosons [1–4]
Deficiencies of theoretical predictions based on pair-wise nucleon-nucleon potentials have been observed in three-nucleon scattering observables
Exact solutions of the Lippmann-Schwinger equations (Faddeev calculations) [5] solely based on modern NN interactions fail to describe high-precision differential cross sections of proton-deuteron elastic scattering at intermediate energies obtained at many laboratories including KVI [6–9], Research Center for Nuclear Physics (RIKEN) [14, 15] and RCNP [16]
Summary
In the last few decades, several nucleon-nucleon potentials (NNPs) have been studied extensively to describe the properties of bound nuclear systems by comparing highprecision two-nucleon scattering data with modern potentials based on the exchange of bosons [1–4]. In elastic and break-up reactions, precision data for a large energy interval for the differential cross section and analyzing power have come from recent experimental studies at KVI [6–8, 10,9,12,13]. Break-up cross sections and analyzing powers for a lished in beam Refs.
