MAGNETIC FORM-FACTORS FOR A TRINUCLEON SYSTEM USING DIFFERENT MESON-EXCHANGE NUCLEON-NUCLEON INTERACTIONS

The magnetic form factors for the He-3 and H-3 nuclei have been calcul ated for different values of momentum transfer. The three-nucleon grou nd-state wave function is expressed in momentum space and is obtained from the solution of the Faddeev equations with realistic two-body pot entials. The potential used is taken from the meson theory to include different meson-exchange contributions satisfying the requirements of current conservation. The different meson-exchange currents and their contributions to the trinucleon magnetic form factors are calculated. The virtual DELTA-excitation and the meson-nucleon vertices form facto rs are included in the He-3 and H-3 magnetic-form-factors calculations . The present results show the importance of the higher momentum trans fer region as being a good source of information to the short-range pr ocesses in the nuclear medium. Our results for the He-3 and H-3 magnet ic form factors are in good agreements with the experimental data. The inclusion of the rho and omega meson exchanges improves the agreement between positions of the minima of the magnetic form factors predicte d and the experimental data.
