We investigate the range of a virtual boson field coming from the transition between two fermions whose masses are different from each other. The spread of a boson emitted by a heavier fermion is longer than that of the one emitted by a lighter fermion. The range of the exchange force potential between two fermions of different masses is longer than the Compton wave length of the boson. The effects of this range shift on the interaction between hyperons and heavy mesons are considered.
