The effects of the small components of Dirac spinors used to describe quark and antiquark wave functions in clusters and the Lorentz contraction of cluster wave functions are considered in the proton-antiproton annihilation into two final state mesons. The effects are studied by referring to the nonrelativistic model as a base of comparison.
