The quadrupole moment of the deuteron indicates the existence of non-central tensor forces in nuclei which destroy the constancy of the total orbital angular momentum. With simple operational representations of the wave functions, the inRuence of two-body tensor forces on the ground state eigenfunctions of the light nuclei H' and He' has been calculated. In H', the tensor forces directly couple...

The effective interaction potential for charged particles is calculated in the deuterium plasma formed in the surface region of the palladium cathode in the electrolysis of heavy water. It is shown that the Coulomb potential is overscreened producing, at certain distances, an attractive potential between deuterium nuclei pairs and also between the deuterium nuclei and the surface atoms. This be...

The hypertriton structure is studied in a three-body model. We use a recently developed method to solve the Faddeev equations in coordinate space. The long distances are treated carefully to achieve convergence and high accuracy. We use several sets of two-body interactions which reproduce the deuteron properties and provide the low-energy Λ-nucleon scattering data close to that of two of Nijme...

Incoherent photoproduction of the η-meson on the deuteron is studied for photon energies from threshold to 800 MeV. The dominant contribution, the γN-ηN amplitude, is described within an isobar model. The final state interaction derived from the CD-Bonn potential is included and found to be important for the description of the production cross section close to threshold. Possible effects from t...

Photoand electroproduction processes of K on the deuteron are investigated theoretically. Modern hyperon-nucleon forces as well as an updated kaon production operator on the nucleon are used. Sizable effects of the hyperon-nucleon final state interaction are seen in various observables. Especially the photoproduction double polarization observable Cz is shown to provide a handle to distinguish ...
