Abstract
The available neutral current induced one-pion production data at intermediate energy are analyzed in a model-independent way in the framework of a recent approach to the corresponding production mechanism. Clear indications about the structure of the isoscalar piece of the weak neutral current are obtained and more stringent evidence of agreement with the standard WS model is seen to emerge. For the first time the relative influence of the different amplitudes contributing to the production mechanism is analyzed, by adopting the neutral current parametrization provided by the WS model.
