Relativistic corrections of three-nucleon wave functions and muon capture in 3He

Wave functions calculated with separable potentials in standard nonrelativistic and covariant Faddeev equations were used to estimate relativistic corrections of the overall muon-capture rate in ³He. They seem to cancel other relativistic corrections obtained from considering small Dirac wave function components in the effective Hamiltonian for the weak interaction.
