RELATIVISTIC 3-PARTICLE DYNAMICAL EQUATIONS .2. APPLICATION TO THE TRINUCLEON SYSTEM

We calculate the contribution of relativistic dynamics on the neutron- deutron scattering length and triton binding energy employing five set s trinucleon potential models and four types of three-dimensional rela tivistic three-body equations suggested in the preceding paper. The re lativistic correction to binding energy may vary a lot and even change sign depending on the relativistic formulation employed. The deviatio ns of these observables from those obtained in nonrelativistic models follow the general universal trend of deviations introduced by off- an d on-shell variations of two- and three-nucleon potentials in a nonrel ativistic model calculation. Consequently, it will be difficult to sep arate unambiguously the effect of off- and on-shell variations of two- and three-nucleon potentials on low-energy three-nucleon observables from the effect of relativistic dynamics.
