The nonrelativistic singlet state average ⟨ ψ| a⋅ σ⊗ b⋅ σ|ψ⟩ =- a⋅ b can be relativistically generalized if one defines spin \it via\/ the relativistic center-of-mass operator. The relativistic correction is quadratic in v/c and can be measured in Einstein-Podolsky-Rosen-Bohm-type experiments with massive spin-1/2 particles. A deviation from the nonrelativistic formula would indicate that for relativistic nonzero-spin particles centers of mass and charge do not coincide.
