Publication abstract: 

The treatment of radiative decays in the tensor formalism is subtle.On the example of radiative J/psi decays the procedure is developed,discussing several methods to construct the amplitudes.In the appendices,spin wave functions,different gauges and form factors for radiative dcays are adressed.
