Three-nucleon system: Irreducible and reducible contributions of the three-nucleon force
A. Deltuva, P. U. Sauer
The three-nucleon bound and scattering equations are solved in momentum space for a coupled-channel Hamiltonian. The Hamiltonian couples the purely nucleonic sector of Hilbert spac…
Three-Nucleon Forces
Peter U. Sauer
The role of three-nucleon forces in ab initio calculations of nuclear systems is investigated. The difference between genuine and induced many-nucleon forces is emphasized. Induced…
Three-Nucleon Forces Revisited - Some Historical Thoughts
Peter U. Sauer
Historic steps in the emergence, the derivation and the use of three-nucleon forces, genuine and effective, for calculations of few-nucleon systems and of the structure of heavier…
Still Few-Nucleon Systems - After So Many Years
Peter U. Sauer
Three- and four-nucleon reactions are discussed. The focus is on the notion of nuclear potentials, on conceptual and technical issues of calculations and on unresolved problems bet…
Four-nucleon system with -isobar excitation
A. Deltuva, A. C. Fonseca, P. U. Sauer
The four-nucleon bound state and scattering below three-body breakup threshold are described based on the realistic coupled-channel potential CD Bonn + which allows the excitat…
Treatment of the Coulomb interaction in three-nucleon reactions
A. Deltuva, A. C. Fonseca, P. U. Sauer
The Coulomb interaction between the two protons is included in the calculation of three-nucleon hadronic and electromagnetic reactions using screening and renormalization approach.…
Momentum-space description of three-nucleon breakup reactions including the Coulomb interaction
A. Deltuva, A. C. Fonseca, P. U. Sauer
The Coulomb interaction between the two protons is included in the calculation of proton-deuteron breakup and of three-body electromagnetic disintegration of . The…
Momentum-space treatment of Coulomb interaction in three-nucleon reactions with two protons
A. Deltuva, A. C. Fonseca, P. U. Sauer
The Coulomb interaction between the two protons is included in the calculation of proton-deuteron elastic scattering, radiative proton-deuteron capture and two-body electromagnetic…
Three-body electrodisintegration of the three-nucleon bound state with -isobar excitation: Processes below pion-production threshold
A. Deltuva, L. P. Yuan, J. Adam +1
Electron scattering from the three-nucleon bound state with two- and three-body disintegration is described. The description uses the purely nucleonic charge-dependent CD-Bonn pote…
Trinucleon photonuclear reactions with -isobar excitation: Processes below pion-production threshold
A. Deltuva, L. P. Yuan, J. Adam +2
Radiative nucleon-deuteron capture and two- and three-body photo disintegration of the three-nucleon bound state are described. The description uses the purely nucleonic charge-dep…
Trinucleon Photo Reactions with -Isobar Excitation: Radiative Nucleon-Deuteron Capture and Two-Body Photo Disintegration of the Three-Nucleon Bound State
L. P. Yuan, K. Chmielewski, M. Oelsner +3
Radiative nucleon-deuteron capture and photo disintegration of the three-nucleo n bound state with two-body final states are described. The description uses nucleon degrees of free…
Photo Reactions on the Deuteron in the Delta-Resonance
K. A. Bugaev, U. Oelfke, P. U. Sauer
Photo disintegration of the deuteron and photo pionproduction on the deuteron are described in the region of the -resonance. The two reactions are unitarily coupled. A novel def…
Meson and Quark Degrees of Freedom and the Radius of the Deuteron
A. J. Buchmann, H. Henning, P. U. Sauer
The existing experimental data for the deuteron charge radius are discussed. The data of elastic electron scattering are inconsistent with the value obtained in a recent atomic phy…
The Dynamical Structure of the Delta-Resonance and its Effect on Two- and Three-Nucleon Systems
G. Kortemeyer, M. T. Pena, P. U. Sauer +1
The pion-nucleon interaction in the P33 partial wave is assumed to proceed simultaneously through the excitation of the Delta-isobar and through a phenomenologically introduced non…
Three-Nucleon Force and the -Mechanism for Pion Production and Pion Absorption
M. T. Peña, P. U. Sauer, A. Stadler +1
The description of the three-nucleon system in terms of nucleon and degrees of freedom is extended to allow for explicit pion production (absorption) from single dynamic de…
