Аннотация:We present a brief survey of some results on electroweak properties of compositesystems that are obtained in the frameworks of our version of the instant form ofrelativistic quantum mechanics (RQM). Our approach describes well the π- and the ρ-mesons in wide range of momentum transfers Q2. At large Q2 the obtained pion formfactor asymptotics coincides with that of QCD predictions. The method permits to performanalytic continuation of pion form factor to complex plane of momentum transfersthat is in accordance with predictions of quantum field theory.
