摘要：

The description of the radiative decays of V -> P gamma* in different forms Poincare invariant quantum mechanics (PIQM) is considered. To construct the matrix element of the electromagnetic current we use the non-diagonal parametrization procedure. The obtained matrix element of the current satisfies the conditions of the Lorentz covariance and conservation. To illustrate this approach in a modified relativistic impulse approximation the description of the radiative transition rho -> pi gamma* is performed. An analytic expression for the transition form factor F-pi rho(Q(2)), matching all forms PIQM, is obtained. Numerical calculations of the transition form factor are made with different model wave functions.
