Relativistic Wave Function of Helium-3

Abstract In the framework of the explicitly covariant formulation of the light-front dynamics, we calculate the relativistic He-3 wave function. It is determined by 32 spin-isospin components, each of which depends on five variables. In the interaction, we take the one-meson exchange kernel as it is, without any potential approximation. At the non-relativistic relative momenta, five of these 32 components dominate and closely resemble their non-relativistic counterparts. Relativistic effects manifest themselves in deviations in the relativistic domain of these components from the non-relativistic ones and in the appearance of new components.
