Abstract

The effect of P11(1440) (Roper) resonance on the response functions for the positivelly charged pion electroproduction from the deuteron is studied using the well known spectator model. The amplitude for the elementary reaction γ* N→π+ N is taken from MAID2003 model. The effect of the NN interaction subsystem in the final state interaction (FSI) is included. Two values for the four momentum transferred Q2 are used. A small effect of the Roper resonance on the structure functions is found.
