Abstract：
The helicity amplitude A^p_1/2 for the electromagnetic transition γ^* N→N^*(1535) is investigated. It is found that a new mechanism γ*→qq plays an important role in order to improve the description of this transition. On one hand, the A^p_1/2 is decreased to fall in the data range at the photon point Q²=0, while on the other hand, the new mechanism makes the function A^p_1/2(Q²) to decrease more slowly vs increasing Q², as required by the data.
